Array indices must be positive integers or logical values.

I'm trying to create a loop that plots the function for each t value on the same graph, I am getting an "Array indices must be positive integers or logical values." error.
t = [1 24 48 72];
x = linspace(0,1,4);
for ii = length(t)
u=1.656e-5;
c(x)=(0.5).*erfc(x./(2.*sqrt(u.*t)));
plot (x, c)
end

This will run:
t = [1 24 48 72];
x = linspace(0,1,4);
for ii = length(t)
u=1.656e-5;
c(ii)=(0.5).*erfc(x(ii)./(2.*sqrt(u.*t(ii))));
plot (x, c)
end
although you may want to experiment with it.
Note that I subscripted ‘x’ and ‘t’, since I assume that is what you intend.

My pleasure.
You must be using different size vectors for ‘t’ and ‘x’.
My code works with the code you posted.
