How to compare in a function definition?

Hi. I have to write a code for the following function:

 calMeasurement = @(Z, M, pTrueDetection, pFalseDetection)[....

Here if z is equal to M, then pTrueDetection should be the output and if it is not them pFalseDetection should be the output. Z and M are 3X3 matrices and have either 1 or 0 as their elements. also these should multiply as the loop moves forward. Here is the main loop.

 for i = 1:worldRows
     for j = 1:worldCols
         x = [i, j];
         lPerception(i, j) = ... 
             calcPMeasurement(Z, getVisibleSubMap(x, Mglobal), ... 
                       pTrueDetection, pFalseDetection);
     end
 end

So if first output is true and next is false them combined output should be pTrueDetection X pFalseDetection. I'm new to Matlab and I can't figure this out. Please help.

Dear Mr or Sir,

Here is an example how you could compare the matrix and use either a true or false variable for replacement. I hope this is what you had in mind/helps you further.

    clc;clear;

Z = round(rand(3,3))
M = round(rand(3,3))

pTrueDetection = 5;
pFalseDetection = 8;

for i=1:3
    for j=1:3
        if Z(i,j)==M(i,j)
            Z(i,j) = pTrueDetection;
            M(i,j) = pTrueDetection;
        else
            Z(i,j) = pFalseDetection;
            M(i,j) = pFalseDetection;
        end
    end
end

Z

Kind regards, Christiaan

Hi Christiaan. Thanks for your prompt reply. However, this will not help me because it is mandatory for me to change only the function. I cannot alter the loop or the rest of the program in any way. I am provided with values as the simulator moves across the plane. I cannot change the values of Z, M, pTrueDetection and pFalseDetection. I have to use them to calculate the total probability.

Thank you for your help.

PS: It is Ms.
