Unable to use a value of type function_handle as an index.

hi all,
I am trying to perform double integration using following syntax:
Gxh=@(xpp,zpp) (xpp+zpp)
GXH=integral2(Gxh,aa,bb,cc,dd);
but i am getting following error message:
"Unable to use a value of type function_handle as an index."
I have already tried to change the names of Gxh and GXH but to no avail. Please help me resolve the issue!

When I assign some integers for aa, bb, cc and dd, your code works for me.
What is your full error message? What are aa, bb, cc and dd in your code?

full error message is: Unable to use a value of type function_handle as an index.
The values of limits aa,bb,cc and dd are not integers, rather these +ve/-ve decimal values.
Also the expression (xpp+zpp) is simplified here, actual expresssion in my code is very long

You have accidentally assigned a value to a variable named integral2
