Undefined variable "phased" or class "phased.ULA"

Hi, I am using MIMORadarVirtualArrayExample code using Phased array system toolbox. My Matlab version is 2017b. But getting this type of error:

MIMORadarVirtualArrayExample Undefined variable "phased" or class "phased.ULA".

Error in MIMORadarVirtualArrayExample (line 36) txarray = phased.ULA(Nt,dt);

Could anyone please help me in solving this issue?

What shows up if you command

which phased.ULA

?

[Shekh Md Mahmudul Islam]

Undefined variable "phased" or class "phased.ULA".

[Walter Roberson]

>> which hither.yon
'hither.yon' not found.

So when which cannot find something you ask about, it says specifically it is not found. That is not the output you are seeing, so you did not command

   which phased.ULA

like I asked you to.

[Shekh Md Mahmudul Islam]

which phased.ULA 'phased.ULA' not found.

Either you do not have the Phased Array toolbox installed, or it is corrupt, or your MATLAB is older than r2012a

do you know where i can find it?

It has been part of the Phased Array Toolbox since R2012a.
