What's the problem with this simple anonymous function?
显示 更早的评论
Here's an simple code:
clear all; clc; close all;
n = 1:3;
for i = 1:numel(n) %numel is used if someother time I'll use negative values for n
f = @(x) x.^n;
fplot(f);
hold on;
f1 = @(x) x.^(1/n);
fplot(f1);
hold on;
end
The function "f" is running OK but "f1" is generating graphics error. For one value of n like:
f1 = @(x) x.^(1/2);
It generates the plot, but not in the loop.
Please let me know what's wrong?

You likely meant to use n(i) in your functions, not n. Another option would be to use 1./n instead of 1/n.
n = 1:3
y = 1./n
z = 1/n(2)
w = 1/n

One thing more to ask how to adjust legend for array n
n = 1:10;
figure(1);
f = @(x) x.^n;
fplot(f);
hold on;
legend(sprintf('$x^{%d}$\n',n),'Interpreter','latex');
xlim([0 10])
The output I got:
How to correct it?
Thanks in advance
