I am trying to numerically evaluate the integral of the normal density function of x with respect to the cumulative distribution of (x+y-m).
I am currently attempting to solve this by trying to integrate the derivative of the cdf times the pdf with respect to x.
Here is my code so far:
k=100;m=20;y=0;syms x;f=normpdf(x);g=diff(normcdf(y-x+m);D=simple(int(f*g,0,(k-m)))Q=double(D);E=normcdf(y+2*m-k)-D
Any suggestions? The error message is Error using NaN Trailing string input must be 'single' or 'double'.
Error in normcdf (line 60)p = NaN(size(z),class(z));
