如何在八度中声明符号矩阵? [英] How do I declare a symbolic matrix in Octave?

问题描述

在MatLab中，您可以轻松声明符号:

In MatLab, you can declare symbols pretty easily:

syms a,b
mat = [a,b]

但是，当我尝试在Octave中复制此错误时，出现错误.这是我正在使用的代码:

I'm getting an error, however, when I try to replicate this in Octave. This is the code I'm using:

> symbols
> a = sym("a")
a =

a
> b = sym("b")
b =

b
> mat = [a,b]
error: octave_base_value::resize (): wrong type argument `ex'
error: octave_base_value::resize (): wrong type argument `<unknown type>'
