Plotting a function containing a single integral with two variables
显示 更早的评论
URGENT HELP, PLEASE! Could you please help me to plot the function in the figure attached ? It contains two variables in the integral but one of them (y) is held constant but still I want to plot the final function f(a,y) with respect to a (the upper limit of the integral) and y!

Use the integral expression obtained here
for the x-integral, insert the limits and solve the resulting equation in y using "fzero" or "fsolve".

You won't have any chance to solve this problem with an exponent of -165 for exp.

I gave you the antiderivative of f with respect to x in the link. You only have to give the appropriate values to a, b and c.
But with this exponent, you won't have a chance to reasonably evaluate fun1 although you will be able to write down q as a function of a and y explicitly .
