permute

permute the dimensions of an array

Calling Sequence

y=permute(x,dims)

Arguments

dims

a scalar or a vector of positive reals.

x

a scalar, a vector, a matrix or a multi-array.

Description

Permutes the dimensions of an array according to dims.

Input argument dims must be a valid permutation where dimension #i becomes #dims(i).

Examples

//example 1:
x=[1 2 3;4 5 6]
y=permute(x,[2 1])

//example 2:
x=matrix(1:12,[2,3,2])
y=permute(x,[3 1 2])

x = matrix(1:12, [3 2 2])
y = permute(x, [3 4 1 2])
// Dimensions are changed according to dims
// #1=rows    becomes #3=pages
// #2=columns becomes #4=books
// #3=pages   becomes #1=rows
// #4=books   becomes #2=columns
