MATLAB: Integration is not evaluated inside a function file

functionintegralintegration

Hi
Could you please help with code below. It is not clear to me why the integration does not evaluated inside the function file. when I used script it is worked but I need to simplified the process by creating the func file to call it at different steps. The integration is identified for the variable (b) as presented in the code below:
function Fg=Fg(a)
syms b;
f_UHM=b/(-0.181363336688152-0.637631218835414*b)+2.64004309728928;
diff_f_UHM=diff(f_UHM)
a1=a-2.5;
FF=diff_f_UHM*asin(b/a1)
q1=int(FF,0,a1)
F=subs(f_UHM,a1)
Fg=F-(2/pi)*q1
end

Best Answer

In the MATLAB Symbolic Math Toolbox, the correct syntax for your int call would be: 
q1 = int(FF,b,0,a1)
However, I do not understand the endis call. Is this MATLAB, or is that a typographical error?
