how to fix Not enough input arguments in integral error ?
显示 更早的评论
my function file is:
function func = myfun1(x,t,L)
func= (exp(-t.*cosh(x))).*cosh(L.*x);
end
and my script is:
xmin=0;
xmax=Inf;
L=[0;2];
T=1:1:10;
size=length(T);
mat=[size,2];
for i=1:2
for t=1:1:10
q=integral(@(x,t)myfun1(x,t,L(i)),xmin,xmax);
mat=[i;q];
end
end
i get the error Not enough input arguments.
i would like to know why and how to fix it thans :)

"integral" only needs one input argument, not two.

Change the function argument of integral to the following:
q=integral(@(x)myfun1(x,t,L(i)),xmin,xmax);
The integral function requires integrating w.r.t a single variable, which is ‘x’ in this case and since ‘t’ is constant w.r.t the integral, it should not be mentioned as variable in the integral function’s function argument.
You can refer to the documentation of integral
