For the questions is there anyway to make the answer looks more clean or better coding?

A(1,3)
B = [1:10; 11:20; 21:30; 31:40; 41:50; 51:60; 61:70; 71:80; 81:90; 91:100; 101:110; 111:120; 121:130; 131:140;]

B=reshape([1:140],[10 14])'

MATLAB: Hello everyone! I need your valuable help here.

April = 4;
Sept = 9;
S = size(mat);
seasons = reshape(mat,[12 14 12 30]);
seasons = seasons(:,:,April:Sept,:);
seasons = reshape(seasons,[12,14,30*(Sept-April+1)]);

Simple, really. The reshape allows you to extract those months. Then reshape things again, to return the array into the desired shape. Or, I could have left it as an array of size [12,14,6,30]. That may help you to use it later. It depends on what you are doing.

MATLAB: Vectorization with two dimensions at the same time

How can I assign null array by using two indices (`a(:,i,i)`)?

You cannot. The way you would get what you're after here is as follows.

[m,n,p]=size(a);
a(:,1:n+1:end)=[];
a=reshape(a,m,[],p)
