Error in Quad, suggestions required ?

syms E
numer = inline('0.99954.*E + ((0.58058-0.044967.*m).*R.*T');
deno = inline('E + (2.54 + 0.94057.*m).*R.*T');
f1 = quad('numer./deno',80,158);
I basically want to calculate the integral of f1 which is a function of E,
it gives me an error . . Not enough inputs to inline function.
When I substitute the the whole function into quad i.e. substituting the function r and fun_e directly, the code works fine but not this way ?
I want to basically define the function in symbolic way step by step and then use it with quad, to integrate,
Any suggestions would help, Thanks, Tonu

Don't mix inlines with symbolics this way.
syms E m R T
f1 = int((0.99954.*E + ((0.58058-0.044967.*m).*R.*T))./(E + (2.54 + 0.94057.*m).*R.*T),E,80,158);

@ Matt Thank you for the prompt reply sir, Actually in my case , the m R t are the inputs and what I wanted to learn was that, Instead of syms E m R T f1 = int((0.99954.*E + ((0.58058-0.044967.*m).*R.*T))./(E + (2.54 + 0.94057.*m).*R.*T),E,80,158); I wanted to code
f1 = int(numer/deno, 80,158) ;
the equation I want to solve is a complicated one (eventually, not shown here) and wanted to simplify the same by coding it as asked in my Original question . Any suggestions would be helpful. thanks,
