M=[ 0 0 0 7.9286 10.1000 14.3714];
M = M(M ~= 0)

M[7.9286;
10.1;
14.3714]
i need
M=[7.9286 10.1000 14.3714] if row vector

do it as follow:
M = [0 0 0 7.9286 10.1000 14.3714];
M = (M(M ~= 0))'
Also I like to ask you do you have values in a matrix or in just in a vector

do you want to convert them to a column vector of non-zero values?
