subs command does not create symbolic variable?
1 view (last 30 days)
I am using MATLAB R2011a. I have symbolic math toolbox installed. When I use the "subs" command to replace a value in a symbolic variable, instead of symbolic variable a normal variable is created ... My code is
asin((2*x)/5 - 4/5)/2
>> subs (f,x,3)
What am missing?
