Matlab:多项式展开例程 [英] Matlab: Polynomial Expansion Routine
本文介绍了Matlab:多项式展开例程的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
In Mathematica, it's easy to expand terms like
(ax^2+bx+c)^n
但是无论如何我可以在Matlab中做到这一点吗?
But is there anyway I can do this in Matlab?
推荐答案
对于任何任意表达式:并非没有Symbolic Toolbox. http://www.mathworks.com/help/toolbox/symbolic/expand.html
For any arbitrary expression: not without the Symbolic Toolbox. http://www.mathworks.com/help/toolbox/symbolic/expand.html
但是,如果要扩展多项式,可以使用conv
函数.只需循环运行即可.
However, if you wish to expand polynomials, you can use the conv
function. Just run it in a loop.
a = 1;
b = 2;
c = 3;
n = 5;
soln = [a b c];
for i=1:n-1
soln = conv(soln,[a b c]);
end
