Name
solve — symbolic linear system solver
Calling Sequence
[x]=solve(A,b)
Parameters
- A,b,x
matrix (resp. vectors) of character strings
Description
solves A*x = b when A is an
upper triangular matrix made of character strings.
Examples
A=['1','a';'0','2']; //Upper triangular
b=['x';'y'];
w=solve(A,b)
a=1;x=2;y=5;
evstr(w)
inv([1,1;0,2])*[2;5]
