Error using fplot: Warning: Error updating FunctionLine.

Hi everyone,
I would like to plot the following function:
function ax_max = maxax(ay,v)
if (v <=130/3.6)
ax_max(ay <= 0.8) = -3.5;
ax_max(ay > 0.8 & ay <= 4.5) = -307/74 + 30/37*ay;
ax_max(ay > 4.5) = 0;
else
ax_max(ay < 0.5) = -2.5;
ax_max(ay >= 0.5 & ay <= 2.5) = -25/8 + 5/4*ay;
ax_max(ay > 2.5) = 0;
end
ax_max=abs(ax_max);
end
by using
fplot(@(ay) -maxax(ay, sqrt(30*ay)), [0 5])
I would like to create four subplots varying the number "30" fplot (30, 123, 400, 900). The fplot function works wenn using "900", but with for example "30"I just get an empty plot and the following warning:
"Warning: Error updatin Function Line. The following error was reported evaluating the function in FunctionLine update: In an assignment A(:) = B, the number of elements in A and B must be the same."
Thank you for your help!

V = [30, 123, 400, 900];
nV = length(V);
for K = 1 : nV
subplot(1,nV,K)
fplot(@(ay) -maxax(ay, sqrt(V(K)*ay)), [0 5]);
title(sprintf('V = %f', V(K)));
end
