The following code for fitting a gaussian is returning the error "There should be atleast two data points". There are definitely more than two data points. Kindly help me resolve this issue.

K>> dbstop if error K>> a = load('calibrate100proc10.lvm'); K>> x = a(:,1); K>> y = a(:,2); K>> plot(x,y); K>> d = hist(y,1000); K>> d1 = d(:,1); K>> d2= d(:,2); K>> f = fit(d1,d2,'gauss1'); Error using fit>iFit (line 259) There should be at least two data points.

According to the documentation for hist, I guess that d2 is an empty vector.
