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]
Is there a simple method or perhaps a built-in function that could generate matrix B from A?

Conversion of a Matrix into a Row Vector. This conversion can be done using reshape() function along with the Transpose operation. This reshape() function is used to reshape the specified matrix using the given size vector.
B = repmat( A , r ) specifies the repetition scheme with row vector r . For example, repmat(A,[2 3]) returns the same result as repmat(A,2,3) .
Column vectors are created using square brackets [ ], with semicolons or newlines to separate elements. A row vector may be converted into a column vector (and vice versa) using the transpose operator '.
Try this: B = A ( : ), or try the reshape function.
