Hi I all, I am new to matlab
I am trying to display the result of zm3(result from the high composite-low/2) at each grid point of data of my data set. My dimensions are x=141, y=71 and t=38. The variable rain is in that dimension. When I run the code below on matlab I get the following error message "Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 141-by-71". How can I fix this?
Thanks in advance
for yr=0:38
for j=141
for i=71

Thanks John for your answer but, that approach still produces the same error message. The issue is that one side is the product of previous calculations zm3 vs the whole data set which is rain. I am trying to represent the value of zm3 on each grid point with data.

The error is generated since the right hand side of
zm3(i,j+1) = rain(:,:,2+yr*38);
is a matrix with dimension 141x71 where the left hand side is just a scalar. Hence assigining a matrix to a scalar position is causing the error.
I assume that you wanted to retrieve rain(:,:,2), rain(:,:,40), rain(:,:,78) etc. till rain(:,:,1446) and assign it to zm3, then you could do the following.
for yr=0:38
