Unbalanced or unexpected parenthesis or bracket.

For some reason I am getting an error when I try and use this piece of code

Q = quad(@Func01_p4, L,U,[],[],a,b,c);

but earlier in the code I use this

A22 = quad(@Intercept3, XR1,XR2,[],[],a,b,c,d,e,f,g);

and it works just fine.

any help? thanks for your time.

Check the line above and see whether it was accidentally marked as continuing with the three dots, or if the previous line has a mis-matched bracket. In particular sometimes a missing "]" cannot be detected on the proper line.
