Question

I have a function f(x,a,b,c) and i want to use plot() to display it. That means i have to compute f(x) for each of my x and store them in a vector to use plot().

How can i apply my function to each element of x individually? My function requires 3 arguments aside from the value of x. I’ve tried arrayfun() but can’t seem to get it working…

x = linspace(0.008,0.08);

a = 0.005;
b = 0.0015;
re = (1.23*40*0.005)/(1.79*10^-5);

y = arrayfun(@f, x, a, b, re);
plot(y);

Any ideas?

Answer 1

You could use an anonymous function:

y = arrayfun(@(x) f(x, a, b, re), x);
