pi

Symbol for pi.

Syntax

R = pi returns a scalar.

R = pi(n) returns an n by n matrix.

R = pi(m, n) returns an m by n matrix.

R = pi(d1, d2, ... dN) returns an N dimensional matrix.

R = pi([d1, d2, ... dN]) returns an N dimensional matrix.

Inputs

m, n, d1, d2, ..., dN
Dimensions of the matrix to be returned.
Type: integer
Dimension: scalar | vector

Outputs

R
The returned matrix of pi values.
Type: double

Examples
