I need a function that removes scalar values of zero along a vector.

Hello, my name is Josh. I am working on some personal research in numbers, and I am using your MATLAB language to do so. I have an extremely long vector, one that I have to put a semicolon after just to not have my command window go bazonkers. It is a one step vector from one to one billion. I am then using the mod function to figure out how many of these numbers, from one to one billion, are divisible by a certain number. I then want to "lay the vectors side by side" and for every zero in the mod vector, I want to remove the corresponding column in the other vector. God, I hope that makes sense. Right now I only have the two vectors, the "X" vector and the mod vector.

You could use I= find(ne(a,o)) or logical indexing should work....
bMod = b(ne(a,o))..... I think this would work. Need to check

X=X(mod(X,n)~=0);
