Matlab integral funtion error

Hi, I can't seem to get the integral function to work correctly.

syms x 
z=1/(3-1)

z = 0.5000

f=@(x)(x.*exp((x.^2)-1))/sin(x)

f = function_handle with value:
    @(x)(x.*exp((x.^2)-1))/sin(x)

fi=integral(f,1,3)

Error using integralCalc/finalInputChecks (line 526)
Output of the function must be the same size as the input. If FUN is an array-valued integrand, set the 'ArrayValued' option to true.

Error in integralCalc/iterateScalarValued (line 315)
finalInputChecks(x,fx);

Error in integralCalc/vadapt (line 132)
[q,errbnd] = iterateScalarValued(u,tinterval,pathlen);

Error in integralCalc (line 75)
[q,errbnd] = vadapt(@AtoBInvTransform,interval);

Error in integral (line 87)
Q = integralCalc(fun,a,b,opstruct);

This is my code, however the integral function keeps giving errors and I am unable to fix the problem. Could someone please help? Thanks in advance!

The error tells you that you need to make sure f outputs the same size as the input.

f=@(x)(x.*exp((x.^2)-1))./sin(x);
%                       ^
%       you forgot this one
fi=integral(f,1,3)

fi = 5.9621e+03

Answer 2

[Walter Roberson]

f=@(x)(x.*exp((x.^2)-1))./sin(x)

Answer 3

[Pere Garau Burguera]

The solution is given in the error message, you should use

fi=integral(f,1,3,'ArrayValued',true);
