hi i have vector of 1000 numbers i want to fit Gaussian model i use
[n,cent]=hist(x,50)
then
bs = glmfit(cent,n,'normal');
then i want to plot the fit yfit = glmval(bs,cent_s); failed Error using glmval (line 64) At least three arguments are required. i want to plot
plot(cent_s,yfit)

You can do the following:
1) Estimate the mean and standard deviation using normfit
2) Calculate the probability estimates using normpdf
3) Plot the data and the estimates using plot
Example:
[m,s] = normfit(x);
y = normpdf(x,m,s);
plot(x,y,'.');
