function mat(x:NumericLike, n:Integer) -> NumericMatrixLike


  • x Argument.
  • n Number of columns into which to unstack. Must be a factor of the size of x.

Returns If x is a scalar then returns a matrix with a single element. If x is a vector then returns a matrix formed by splitting it into n equal contiguous subvectors and unstacking them to form the columns of a matrix. If x is a matrix then reshapes it to the given number of columns as if calling mat(vec(x), n).
