reshape

Reshapes a vector or a matrix to a different size matrix.

Syntax

• M2 = reshape(M1, s1, ... ,sN)
• M2 = reshape(M1, ..., [], ...)
• M2 = reshape(M1, size)

Input argument

• M1 - a vector or an matrix
• size - a size vector
• s1, ... ,sN - a s1 - by - ... - by - sN array where s1, ..., sN indicates the size of each dimension.

Output argument

• M2 - Matrix reshaped

Description

reshape performs a reshape to a different size matrix. If only one dimension is specified, reshape will determine complementary size automatically. [ ] is used to unspecify the dimension.

Example

M1 = ones(3, 4, 5);
M2 = reshape(M1, [5, 3, 4])
M2 = reshape(M1, 5, [], 4)
