What is the alternative of xtickformat() in the R2015a version?

Hello,

I was trying this code on the version R2015a:

t = 0:seconds(30):minutes(3);
y = rand(1,7);
plot(t,y)
xtickformat('mm:ss')

But I got this error:

Undefined function or variable 'xtickformat'.

How do I solve it please?

datetick('x', 'mm:ss');

Note that in that release (and earlier releases) each time you zoom or pan, you will need to re-execute the datetick() command in order to update the tick labels properly.

In sufficiently new versions, if datetime or duration objects are used as the x axes, then the axes labels will be automatically updated as you zoom or pan. However, that facility had not been implemented in R2015a.

Thank you very much. I have another question please.

I tried this code:

t = 0:minutes(0):hours(10); 
y = [10; 60; 12; 53; 47; 81; 25; 49; 83; 21];
plot(t,y)
datetick('x', 'HH:MM');

And I got a blank figure like this:

Why this happened and how to generalize this code for any hours-minutes combination?

You are incrementing by minutes(0)

You probably meant minutes(60) . However, 0:minutes(60):hours(10) would be 11 entries and you only have 10 entries in y.
