I have generated several elements in
a Matrix as follows:
A= [ 0 0 0 0 0 7 8 9 0 0 0 0 0]
but I require the final answer as
A=[7 8 9]
How do I remove the the zeros in the matrix?
Please advise
Regards
Supramaniam

A(A~=0)

| Why dont you just write a loop and filter the non-zero elements of A into a
new matrix B?

No! Don't use a loop. Use the solution proposed by Derek instead. Loops
are generally a very bad idea in MATLAB and should be used only when
nothing else is possible.
