有人知道通过以下方式将原始矩阵的所有行(从1到M)放入新矩阵的第一行，从而从M x N矩阵创建一个行矩阵(向量)的最佳方法是什么:

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]

示例:

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

有没有一种简单的方法或内置函数可以从A生成矩阵B?

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

推荐答案

请尝试以下操作:B = A ( : )，或尝试使用reshape函数.

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