Answer to Question #5930 in MatLAB | Mathematica | MathCAD | Maple for Purvi

Question

Hi,
I am working on my project on matlab where I have to divide an array of size 1X711000 in to subarrays of size of 1X100.
Can I use the command mat2cell command for it?
Please give the proper command for it.

Answer 1

Suppose your array is called A and has size 1 x N*M, so it is a row.
To
divide it into N cell arrays of length M use the command:
C =
mat2cell(A,[1],ones(1,N)*M);

Now to access the i-th M-tuple you should
run
C{i}

In your case you should run
C =
mat2cell(A,[1],ones(1,7110)*100);
===============================

Another
approach is to convert A into M x N array (M rows and N columns) by the
command
D = reshape(A,M,N)
Then to access the i-th M-tuple
run
D(:,i)
In your case use the command
D =
reshape(A,100,7110)
