flipdim

// 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(1:24, [3 2 4])
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)

// Integer-encoded numbers:
x = int16(grand(4, 3, 2, "uin", -9, 9))
y = flipdim(x, 1)

// Booleans:
x = (grand(3, 4, "uin", -9, 9) > 0)
y = flipdim(x, 2)

// Texts:
x = matrix(strsplit("a":"x", 1:23), 4, 6);
x = x+x
flipdim(x, 2)

// Polynomials:
x = inv_coeff(grand(3, 9, "uin", 0, 3), 2)

// Rationals:
n = inv_coeff(grand(3, 9, "uin", 0, 3), 2);

// Error if sb does not divide the targeted dimension of x.
