How to rectify the following code

Respected Sir/Madam

Please give the ideas about How to rectify the following Error code after the 25th iterations in my program.

??? Error using ==> reshape To RESHAPE the number of elements must not change.

Error in ==> sym.maple at 94 result = reshape(result,size(varargin{3}));

Error in ==> sym.int at 39 r = reshape(maple('map','int',f(:),x),size(f));

Error in ==> Esu at 55 f1(m)=vpa(h1*int(exp(t)*int(exp(-2*t)*int(exp(t)*R1(m-1))))+g(m-1)*f1(m-1),5);

Thanking you

with regards S.Eswaramoorthi

The problem is that you are attempting to reshape a vector but you are changing the number of elements. For example:

    x = randn(100,1);
    y = reshape(x,20,5);

works because (20)(5) = 100

but

x = randn(100,1);
y = reshape(x,21,5);

generates the error you are getting. The same principle applies for symbolic arrays.
