Diag command in matlab
WebJul 16, 2024 · 在Matlab中，diag函数可以用来创建对角矩阵或从矩阵中提取对角线元素。 要创建一个对角矩阵，可以使用形如diag(v)的语法，其中v是一个列向量，表示对角线上的元素。该函数将返回一个方阵，其中对角线上的元素为v中的元素，其余元素为零。 WebMatlab is a program that is geared for performing numerical calculations in an easy and straightforward way. It is text-based so you type in commands, hit return, and this creates output or plots. For example, if you type 2+2 and hit return, you get 4. If you type cos (pi) you get -1. Operators
