Creating a loop and loop variable

Hi guys,

How would I write a for loop in which the loop variable runs from 0 to pi/2 in steps of 0.01?

Am i right in saying:

for

A = 0:0.01:pi/2

end

Is this correct?

for k = 0:0.01:pi/2
    k
end

for  a=0:a+0.01:pi/2
    disp(a)
end

Thank you! And if i were to add inside this loop do i need to disp(i) every time i enter a new line of code?

[Yusuf Suer Erdem]

disp(i) is just to show you that the loop works. you could do anything you want with that i value.

The colon operation given in the answer uses the imaginary unit in the step, which leads to this warning:

0:i+0.01:pi/2

Warning: Colon operands must be real scalars.

ans = 1×158

0 0.0100 0.0200 0.0300 0.0400 0.0500 0.0600 0.0700 0.0800 0.0900 0.1000 0.1100 0.1200 0.1300 0.1400 0.1500 0.1600 0.1700 0.1800 0.1900 0.2000 0.2100 0.2200 0.2300 0.2400 0.2500 0.2600 0.2700 0.2800 0.2900

I don't see any reason why the step needs to use the imaginary unit.

maybe used i as a character. i changed it with a. it should be okey now.
