I'm trying to make a function that compares the standard deviation to a value to see if its below 1std of the mean. To do this I created some loops that should go through each value in an array and compare it with the same positioned value in the std array, and mark it as true or false. Here is the code:

function [within1std] = StdComparison(Parameters, Mean)
%Function will take the mean away from value, make it positive and compare
%to the standard deviation
%   Detailed explanation goes here
StandardDeviation = movstd(Parameters, [5 4],1);
within1std = [];
for i = Parameters(:,i)
    for j = Parameters(j,:)
        Std1 = StandardDeviation(j,i);
        DiffFromMean1 = Parameters(j,i) - Mean(j,i);
        DiffFromMean1 = abs(DiffFromMean1);
        if DiffFromMean1 <= Std1
            within1std(j,i) = 'True';
        else
            within1std(j,i) = 'False';
        end
    end
end
end

Is such case you can avoid loop, using conditional statements-

result=array==std_array

The result will be another array of same size, with having elements 0 or 1. If 0, both same positioned values are not same, otherwise equal number.
