Please execute this line of code in Matlab R2015b:

>> [minutes(seconds(1)):minutes(1):minutes(seconds(200))]

Why it goes crazy and gives back a column vector of size 4777?

I need to create ticks for my plot; and I thought this had to work!

The help of minutes tells us

If X is a numeric array, then M is a duration array in units of minutes.
If X is a duration array, then M is a double array with each element equal to the number of minutes in the corresponding element of X.

so

minutes(seconds(1))

and

minutes(seconds(200)

give a double, while

minutes(1)

gives a duration. So you have

which messes all up. To increment by 1 minute, use

minutes(seconds(1)):minutes(seconds(200))

Thank you. This is really confusing. I believe what I tried to do is the one of the most common use of the time types like minutes, second, etc.; and, yet it can not be done!
