mul (alias: "x*y")

From STX Wiki
Jump to navigationJump to search

Compute the inverse of x.

Usage
mul(x, y)
Result
If both arguments x and y are vectors, the tensor (or dyadic) product of the vectors is computed and the result r is a matrix with nrow(x) rows and nrow(y) columns.
ri,j = xi * yj
For all other combinations of data types, the operator * is applied to x and y and the product x*y is returned. If the multiplication is not possible (e.g. invalid combination of data types), the function mul failes.
