How do you concatenate the rows of a matrix into a vector in MATLAB?

Hi,

Does anyone know what is the best way to create one row matrix (vector) from M x N matrix by putting all rows, from 1 to M, of the original matrix into first row of new matrix the following way:

A = [row1; row2, ..., rowM]
B = [row1, row2, ..., rowM]

Example:

A = [1 1 0 0; 0 1 0 1]
B = [1 1 0 0 0 1 0 1]

I would be very thankful if anyone suggested any simple method or perhaps points out a function if it already exists that could generate matrix B from original matrix A.

Answer 1

Try this: B = A ( : ), or try the reshape function.

Answer 2

You can use the function RESHAPE:

B = reshape(A.',1,[]);
