Is there an efficient way to figure out if a matrix is dependent or linearly independent?

perhaps a function or something?

Thanks

Linear independence and linear dependence are

not matrix properties. They are properties of

its rows and columns.

I use both rank and cond (condition number) when

determining the degree of multicollinearity within

a matrix.

Hope this helps.

You can use rank.
