plot matlab function handle that outputs vector

Question

So I have a matlab function I wrote that takes in a number and returns an array of numbers (transposed). I need to plot this function. I was trying to use fplot but it was giving me errors:

Error in fplot (line 105)
x = xmin+minstep; y(2,:) = feval(fun,x,args{4:end});

Am I using the wrong plot function?

the function solves an equation of motion problem. I have this diff eq:

Mx'' + Cx'+ Kx = 0

where M, C, and K are 4x4 matrices and my function solves the general solution and outputs a vector of 4 values.

Answer 1

我通过将函数更改为接受 t 值数组来解决我的问题，然后我使用了 plot 函数而不是 fplot
