How to concatenate two or more MATLAB files in a single file?

Suppose file A(1 * 36), B(1 * 30), C(1* 25), D(1* 40), E(1* 45) and now i want to merge all these values in one file, to make a single file e.g, X(5 * 45)

Can't directly because Matlab arrays can't be jagged but rectangular.

You can either augment the shorter to the longest by padding w/ zero or an indicator value (NaN often used for this purpose) or use a cell array if that's not palatable.

Either way you'll have to read the files into memory first--assuming you've don so then

L=45;  % I just looked; you'll want to code max(length(A), ...) to automate
X=[A nan(1,L-length(A)); ...
   B nan(1,L-length(B)); ...
   ...
   E];

or, the cell array approach

X={A;B;C;D;E};

Only your subsequent usage can determine which is the better approach.
