variable q and y

%%i am using this

fun=@(x) exp(-x)*y

A=GLGD_int(fun,0,1,5)

vpa(A,3)

fun1= matlabFunction(A,'vars', [y]);

B=GLGD_int(fun1,2,5,5)

vpa(B,3)

%% GLGD_int is call by another .m file

%% this program is okay, but as I use the function of the form as "fun=@(x) exp(-x)*y*sin(q)" as

fun=@(x) exp(-x)*y*sin(q)

A=GLGD_int(fun,0,1,5)

vpa(A,3)

fun1= matlabFunction(A,'vars', [y]);

B=GLGD_int(fun1,2,5,5)

vpa(B,3)

%% then error come as

%%Error using sym/matlabFunction>checkVarsSubset (line 207)

%%The free variable q must be included in the 'vars' value.

%%Error in sym/matlabFunction>checkVars (line 195)

%%checkVarsSubset(vexpanded,funvars);

%%Error in sym/matlabFunction (line 137)

%%vars = checkVars(funvars,opts);

%%Error in chi2 (line 8)

%%fun1= matlabFunction(A,'vars', [y]);

Not satisfied by this answer as I wants to take that in same file. Because as i dont use q variable in program then file is run succesfully but as i introduced q then i have error.

you cannot do that . When q does not have a specific value then you cannot do numeric integration .

I suggest you search the matlab help for information about parameterizing functions .

[SHARAD KUMAR UPADHYAY]

Fine, to call by another file is okay. I have tried and that works.
