Ratios in matrix | Matrix/Vector | if statement/loop |

I was wondering how would you explain below function to work with matrix instead of vector input, essentially I just find all values that is over a certain value in that column and add it up and divide it by total rows to give me ratio. Below is working for vector input but I kinda not sure how to complete the one with matrix input. Should I use logical instead?

The method I chosen don't think will work if there is more than 2 columns but I wish it could accommodate any size.

function Ratio = ratiovector(Vector)

N = numel(Vector);
c=0

for a = 1:N

    if Vectors(a) >= 20
        c=c + 1;
    end
    end


Ratio = c/N;
end

Matrix Input

function Ratio = ratiovector2(Matrix)

rows = Matrix(:,1)
columns = Matrix(:,2)
c = 0
d = 0

for a = 1:rows
    for b =1:columns

    if Matrix(a) >= 20
        c= c + 1;
    if Matrix(b) >= 20
        d= d + 1;
    end
    end


Ratio = ?;
end

python seem to ignore part of my if statement

I have an if statement which has 3 requirements.

if  (-30 < distancey1_1 < 30) and (german_startx1 < 705) and (distance1_1 < 600) :               # is german 1 in position and are the russians in range (between 30 and minus 30 doesnt work)
    print(distancey1_1)
    print('1_shoots_1')
    shoot(bulletx1, bullety1, 10, 10, yellow)

Somehow it runs this if statement, even when all 3 requirements are not met.

i get this as an output sometimes. its basically admitting that its ignoring the -30 < distancey1_1 < 30 rule

1 shoots 1
-152.0
1 shoots 1
-152.0
1 shoots 1
-152.0
1 shoots 1
-152.0
1 shoots 1

this is part of a stupid little recreation im making of that scene from enemy at the gates.

the full code is below. it just makes squares which moves side ways, some of them shoot.

Issue comparing values in php

I have this php code meant to compare two values,a variable $rate received from a form which can either have values 'applaud' or 'boo' so I want to check if the value is neither of it and kill the page with an error message.I've tried that but ...localhost can not handle this request

HERE IS MY CODE:

<?php 
$rate=$_POST['rate'];
echo $rate;

?>

<?php

if($rate != 'applaud' OR $rate != 'boo')
{

die("Sorry there was a problem var rate was not well stated");
}

else
{
    echo 'yay ,well stated!!!';
}
?>

Excel select first value belong to one name

I need get first value which belong to one fiscal week and the others have zero. I have IF(COUNTIF(B2:B40,B2)>1,IF(COUNTIF(B$2:B2,B2)=1,C2,0),""). But I also want the same in the same cell for another person.

My problem is, that my formula works only for one person (column D) but I need to work for all name with the same fiscal week (column E). Can anybody please help? Thx

Google charts draw becomes very slow in If clause

I have a Google column chart which is working just fine, although in some cases it could happen that the data set returned from the SalesQueryN.asp is empty. To avoid an error message being displayed, I tried to use an

if (condition) {} else {} 

clause to check if the data set is empty, otherwise it should draw the chart.

Without the if, the chart is drawn instantly, but this line

chart.draw(data, google.charts.Bar.convertOptions(options));

is within the else {} clause, the browser hangs for some 30 seconds. Eventually it does display part of the chart, but the performance is not acceptable, and it doesn't display the proper full chart.

Here is the Ajax code that I use to draw the chart.

    google.charts.setOnLoadCallback(function() { drawsdr(cYear,cMonth,'CST')});

    function drawsdr(rY, rM, rS) {
      if (rY === undefined) {
          rY = Date().getFullYear();
      }
      if (rM === undefined) {
          rM = Date().getMonth();
      }
      if (rS === undefined) {
          rS = 'CST';
      }
      $.ajax({
          url: "api/SalesQueryN.asp?P=T&Y=" + rY + "&M=" + rM + "&S=" + rS,
          dataType: "json",
          async: true,
          success: function (jsonData) {
             var data = new google.visualization.arrayToDataTable(jsonData);
             var chart = new google.charts.Bar(document.getElementById('s'+rS));
             var options = { 
                 title: rY + '-' + rM,
                 legend: { position: 'bottom' },
                 bar: { groupWidth: '80%' },
                 fontSize: xFS, fontName: xFo,
                 isStacked: false,
                 seriesType: 'bars',
                 vAxis: { format: '#,###' },
                 hAxis: { textStyle: { fontSize: xFS } }
             };
             if (data.getColumnLabel(0) == "empty") {
                document.getElementById("sCST").innerHTML = "<p>There is no data to display for " + rY + "-" + rM + "</p>";
             } else {
                chart.draw(data, google.charts.Bar.convertOptions(options));
             }
          },
          error: function (response) {
             alert(Object.keys(response));
             //alert(response.statusText);
             alert(response.responseText);
          }
        });
      }

I'm not quite sure why the if clause is affecting the performance so much.

My question now is how can I make the check on the data table without slowing down the chart's drawing?

PHP inline if statement always returns false

can't seem to start this working properly, any idea what could be the problem? The variable APP_NAME is equal to string 'test', if I do this if statement in a regular way it works as it should.

<?=form_radio('filter', 'y', $info['enable_categories'] == 'y' ? true : false, 'id="app" '.APP_NAME == "test" ? '' : 'disabled'.'')?>

The disabled parameter has to be put into the same last parameter as id.

But this way I get the false value even if APP_NAME equals 'test'.
