Hello guys,
I'am new to Matlab and need your help
how can i set the axis such that every step is for example '8.03 units'?
thanks

To set the axis ticks with a specific step size like 8.03 units, you can use the xticks (or yticks) function. Here’s a quick example for the x-axis:
x_min = 0; % starting value of the axis
x_max =
100; % ending value of the axis (adjust as needed)
step =
8.03; % your desired step size
xticks(x_min:step:x_max);
This will set the ticks at intervals of 8.03 units along the x-axis. You can do the same for the y-axis with yticks. @mr flip

Hello,
You can set the x-axis ticks using xticks function:
x = 0:0.1:5;
plot(x, sin(x));
xticks(0:0.83:5);
xlim([0 5]);
In a similar way you can set your y or z ticks. You can read more about it here: https://www.mathworks.com/help/matlab/ref/xticks.html

thanks this was very helpful :) but i think "xlim()" function is trivial becaus the boundaries are already limited by the "xticks()" function, what do you think?

The boundaries are limited by the extreme points of x which can be changed by xlim(). xticks() merely specifies a list of increasing values where the ticks should be marked, it could be out of the figure frame too! Consider the following example:
x = [4 2 6 0 -2];
plot(x, sin(x));
xticks([-4 8 10]);
You can hold and drag the graph to see those ticks.
I used xlim() because somehow 0 was being trimmed out from the graph at that moment, but now it's working fine :)
