I have the symbolic toolbox and syms normally works and it works on part of the code but says unrecognised in the bottom part of the code.
In the start of the code i put:
zoj="syms";
for w0=1:N-1 % N is any number
zoj=strcat(zoj," golp",string(w0));
end
eval(zoj);
Then I made a symbolic column matrix u2 with the symbols glop1 to glopN-1 where there was no error. I also made a function pagetimes,in a different file but in the same folder, which outputs a N-1*N-1 matrix as pagemtimes did not work for symbolic matrix. DD is a N-1*N-1*N-1 matrix. The functions used in the code work with no error and the variables and matrices are defined.
Then I did this:
seq10="glop1"
for w2=2:N-1
seq10=strcat(seq10,",glop",string(w2));
end
seq1="["
for w3=1:N-1
seq1=strcat(seq1," diff((MM2+(1/2)*(T1)*SS2*a)*u2+pagetimes(((1/2)*(T1)*DD),u2)*u2-(MM2-(1/2)* (T1)*SS2*a)*u00+pagetimes(((1/2)*(T1)*DD),u00)*u00-(1/2)*(T1)*(fvs((j11-1)*(T1),a)+fvs(j11*(T1),a)),glop",string(w3),")"); % This is to make a Jacobian square matrix out of column matrices in string form.
end
seq1=strcat("seq11(",seq10,")=",seq1,"];seq11=matlabFunction(seq11)")% This is to make a function to input numbers into the seq11 function later.
eval(seq1)
The red text is:
Error using eval
Unrecognized function or variable 'glop1'.
Error in function (line 137)
eval(seq1)
