I have two matrices and I would like to create a matrix containing the above threshold value of each element of both matrices

I have two matrices of the same size and for each element I would like to do the following:

if the value of the element in matrix2 is above the threshold, keep the value

else assign the value of matrix1 to this element.

Is this possible without for loops?

Is this possible without for loops?

Yes. One way is as follows:

mask=(matrix2>=threshold);

result = matrix2.*mask + matrix1.*(~mask);

Another way,

result=matrix2;
idx=(matrix2<threshold);
result(idx)=matrix1(idx);
