flipdim

flip x components along a given dimension

Calling Sequence

y=flipdim(x,dim)

Arguments

:x a scalar, a vector or an array of real or complex numbers. : :dim a positive integer : :y a scalar, a vector or an array of reals :

Description

Given x, a scalar/vector/array of real or complex numbers and dim a positive integer, this function flips the x components along the dimension number dim of x ( x and y have the same size)

Examples

// example 1: flip x components along the first dimension
x=[1 2 3 4; 5 6 7 8];
dim=1;
y=flipdim(x,dim)

// example 2: flip x components along the second dimension
dim=2;
y=flipdim(x,dim)

// example 3: flip x components along the third dimension
x=`matrix`_(1:48,[3 2,4,2]);
dim=3;
y=flipdim(x,dim)

// Example 4: the first example with complex
x=[1+%i 2*%i 3 4; 5 6-%i 7 8*%pi*%i];
dim=1;
y=flipdim(x,dim)
