about ztrans command?
显示 更早的评论
I tried ztrans command in matlab r2009a and 2010a?
when I type
>>help ztrans
ztrans not found.
Then which version of Matlab supports ztrans command?
If it works in r2009a and 2010a then why I am not getting in my software (r2009a,2010a)?

ztrans is a function from the Symbolic Math Toolbox™, you must have that toolbox installed and with a valid licence.

Is the Symbolic Math TB listed when you type ver in the cmd window?

you should have it unless you deleted it or there's a problem with the installed matlab and toolboxes, use the function pathtool to see if the symbolic toolbox path is there, also try the rehash function, maybe rehash toolbox.
Another way to see if the ztrans function is there, search for ztrans.m with your OS search function.
