Errorin hamsym (line 42) dsolve( diff(y) == x^2, y(0) == 1 ) but I received the bellow error: I think it may be due to improper use of symbolic vector which changes "y" from a scalar to a 1x1 system. Thanks a lot for your help....
Unless there are reasons to use syms other then to compute the polynomials, it's probably better and easier to avoid syms altogether.

I have an old version of Matlab (2008), when I try to create an ODE function and solve it, it does not work and errors appear as follows: >> syms y(t) ??? Undefined function or method 'syms' for input arguments of type 'char'. >> y(t) = dsolve(diff(y,t) == t*y) ??
symss t H = transferH(K); y = ilaplace(H*(1/s));%Unit step end However the output just becomes "warning unable to find explicit solution". I have tried done some manually testing with wolfram and the K value should be around 30-31, but im n...
