Hi everyone! I need your help.

I have the following matrices:

Mat_A=194 x 201 x 360 rows, columns and monthly value respectively

Mat_B= 194 x 201 x 30 rows, columns and seasonal value respectively

I need to divide selected monthly values (from April to September) from Mat_A by Mat_B (seasonal value).

I tried the following:

Year=1:30;
April=(year-1)*12+3;
Sept=(year-1)*12+9;
for h =1:length(Mat_A)
    for k= Mat_B(:,:,1:36)
        Mat_C(h)= Mat_A(:,:,April:Sept)./ Mat_B(:,:,:)
    end 
end

I tried different ways, and couldn’t fix it. For this code, I am getting “Subscript indices must either be real positive integers or logicals.” error. Thank you.

Kindly, Engdaw

Adapt this into your problem:

A=randi([1 5],194,201,360);
B=randi([1 5],194,201,30);
for i=120:270
    A(:,:,i)./B(:,:,1:30);
end
