Retrieving odd numbers from a matrix

Within a matrix, I want to be able to retrieve only odd numbers within the matrix, and place that into its own matrix.

What I have right now is:

x = randn(1,100); odd = mod(x, (x/2))

I'm not able to get the new matrix, odd, to print with the odd values from x, even though I divided by 2, in order to return any values with a remainder. I get an error pointing to the second argument of the function mod.

Where am I going wrong with my code?

Thanks for the help!

Instead of doing mod(x, x/2) use mod (x, 2)

This will output the odd numbers rather than just dividing it into two. Hope that helps!

Use MATLAB's great indexing ability:

X = randn(1,100);
Y = X(mod(X,2)==1);
