Answer 1

[Alexandra Harkai]

repelem(t, 4)

[Mohammed Yousuf]

sorry Mr Alexandera, its not working, showing error as ??? Undefined function or method 'repelem' for input arguments of type 'double'.

[Alexandra Harkai]

Without needing to define t the way you mention in the original answer, you can write it like this:

t = (1:10)';
repelem(t, 4)

What MATLAB version are you using?

(Btw it's 'Miss'. Not 'Mr'.)

[Mohammed Yousuf]

my matlab version isR2009a may be that may be the reason

[Guillaume]

repelem was introduced in R2015a. It is a good idea to mention which matlab version you're using in the question particularly when it's that out of date.
