Question

求MATLAB大神，将一个矩阵的元素赋值给另一个矩阵的成为对角元。不胜感激！！！

程序：
syms R1 s L2 C3 R4 L5 L6;
r=[1/R1 1/(s*L2) s*C3 1/R4 1/(s*L5) 1/(s*L6)];%{电路各支路的导纳%}
Yb=zeros(6,6);
for i=1:6;
Yb(i,i)=r(1,i);
end
Yb
报错：
Error in Y1 (line 5)
Yb(i,i)=r(i);
DOUBLE cannot convert the input expression into a double array.

Answer 1

clc; clear all
syms R1 s L2 C3 R4 L5 L6;
r=[1/R1 1/(s*L2) s*C3 1/R4 1/(s*L5) 1/(s*L6)] %电路各支路的导纳%
Yb=zeros(6,6);
syms Yb
for i=1:6
Yb(i,i)=r(1,i);
end
Yb
