fit gaussian to a known sigma

Hello, I am trying to visualize/plot a standard gaussian fit [a*exp(-((x)/c)^2)] with a known value for c. In this case, it should be fine if a=1.
I am having trouble plotting this since I do not have coordinate pairs to make the graph. I would prefer using a code to do this rather than the curve fitting toolbox if possible because I want to visualize multiple curves at once. Thank you so much for your help!

Try this:
gaussfcn = @(b,x) b(1).*exp(-((x)./b(2)).^2);
xv = linspace(-10, 10);
b = [1; 4.2];
yv = gaussfcn(b, xv);
figure(1)
plot(xv, gaussfcn(b, xv))
grid
