Integral equation with independent variable to be solved

Hi,

I have the following function of x and y.

Clearly x is the integration variable and "y" should be defined as a variable to be solved (not directly in this equation).

Does anybody know how can I define f so as to solve for y further.

Any help would be appreciated, Farid

As written,

y = f / integral_{x=x1}^{x=x2} [x*erfc((x-a)/sqrt(t))] dx

Thank you for your response. However, I am afraid it is not what I meant. My question is not about finding "y" but defining f as a function of y (f(y)). Actually I don't know how to define definite integration with respect to "x" and obtain f(y).

[Torsten]

f = @(y)integral(@(x)x*(A+y-A).*erfc((x-a)/sqrt(t)),x1,x2)
