How to express ZOH transfer function in Matlab?

I am tring to express ZOH transfer funcation in S domain and bode plot it. The transfer functino is shown below:

(1-exp(-s*Ts))/s

The question is how to express it, is there any function related to it?

Thanks.

Your question is not clear

I just replace the image by symbolic expression. Please take a look.

May I know what should I do to make it clear?

Which image?

[Siyu He]

I don't know how to upload image and the tf is shown by symbolic expression now.

s=tf('s');
Ts=0.1 %replace with desired value
sys=(1-exp(-s*Ts))/s
bode(sys)

Thanks for your reply. I tried this method and error information shown below,

??? Error using ==> InputOutputModel.plus at 61 System interconnection gives rise to internal delays and can only be represented in state space. Convert at least one of the models to state space using the "ss" command.

Error in ==> InputOutputModel.InputOutputModel>InputOutputModel.minus at 324 M = M1 + (-M2);

P.S. I am using Matlab R2010b version.

[Arkadiy Turevskiy]

In 10b:

s=tf('s');
Ts=0.1
sys1=exp(-Ts*s)/s
sys2=1/s
sys=ss(sys2)-ss(sys1);
bode(sys)

Thanks for your help, it works.
