Hi fatema,
I understand that you want to create a vector with predefined data instead of using zeros, ones, rand functions.
let's create a vector A(5 x 1)
A=[1;2;3;4;5]
let's create a vector B(5 x 5) from the predefined data(A)
B=A(:,[1,1,1,1,1])
The same result as above can be achieved by doing the following
RowCount = size(A, 1)
ColumnIndexes = ones(1, RowCount)
B=A(:, ColumnIndexes)
The best way to use the predefined data is to index it to get the desired results. refer to this document for more info.
