transmitRepeat function not found in MATLAB2021a?

I have installed MATLAB2021 just for transmitRepeat but when i write help transmitRepeat is command window it ans me transmitRepeat not found.

Is that function is changed with anyother function?

It is not part of basic MATLAB. You need to install

Communications Toolbox Support Package for USRP Embedded Series Radio

And as we discussed in https://www.mathworks.com/matlabcentral/answers/773048-transmitrepeat-function-not-found-n-matlab-2020a transmitRepeat() is not a stand-alone function: it is an object method that can be applied to comm.SDRTxE3xx system objects https://www.mathworks.com/help/supportpkg/usrpembeddedseriesradio/ug/comm.sdrtxe3xx-system-object.html

Unless you changed your hardware since our previous discussion, you do not have an E3xx device, you have a B2xx device. And as we already discussed, there is no transmitRepeat() for the B2xx devices.

Asking the same question again and pretending not to have engaged in the previous discussion will not magically cause the desired function to appear. The B2xx boards are not defined for this function; you would need to reprogram the FPGA to do this function on the B2xx board... but such a reprogramming would be incompatible with accessing from MATLAB (the access from MATLAB checks software integrity.)
