Hi, I want to conduct a frequenct analysis using the following code:
odes = [diff(y,2) == (-k/m)*y + (w/m)*z; diff(z,2) == (-J/I)*z + (w/I)*y];
conds = [cond1 cond2 cond3 cond4];
qwe = dsolve(odes, conds);
However, when I am using fft(), I need to use numerical data. Is there a way to conduct a symbolic fourier transform, or do I need to convert the symbolic function to numeric data?
If I do need to convert my symbolic function to numeric data, how do I do this?
