Hi everyone,
I run a matlab code containing symbolic variables in it. When I use "subs" code to substitute all of the symbolic variables in a variable with numerical values, after computation, I obtain a symbolic format result of the variable in the workspace in matlab. but when i use findym() to check which symbolic variable in it, I find no symbolic ones exist in it. just as the following for instance for brevity because my code is too long:
syms a b;c=a+b;d=subs(c,[a,b],[1,2]);
normally d should be a numerical value, but it is symbolic
It is quite strange.
Could anyone give a reason for this? Thanks so much for your help!
