I have a matrix with three columns and n rows.
I would like to produce four matrices with three columns and different rows. it is not important that matrices do not have the same rows.
For instance:
A has 210 rows.
I want to have B with 40 rows, C with 60 rows, D with 30 rows, and E with 80 rows.
Thanks a lot for help.

A=rand(210,3);
out=mat2cell(A,[40 60 30 80]',3)
You have your 4 matrices
out{1}
out{2}
out{3}
out{4}

A = zeros(210,3); %example
split = [40 60 30 80];
A_split = mat2cell(A,split);
[B, C, D, E] = A_split{:};
doc mat2cell

Many thanks for the response. But A was just an example.
I want a code to work for every matrix with n rows and three columns.
