I have a discrete scalar input into a simulink buffer and would like the buffer to output a 100x1 vector of the scalar inputs. However, I keep getting this error and I can't figure out why, because the input into the buffer is discrete.

Try feeding the Buffer block with a Constant block. Changing the sample time of the Constant block from "inf" to 0.1 (for example) will result in the disappearance of this error message. "inf" means constant sample time.

Thanks for your help. The diccrete sample time seems to be correct now. You're right - The block feeding into it was an enabled synchronous subsystem that I think was not definitely discrete, even though it had a discrete output.

Error message: All sample times must be discrete. No continuous or constant sample times are allowed.

I am getting the above mentioned error while building the model in simulink. This error pertains to buffer block which is receiving bitwise data from Dspace via RS232 serial port. Please let me know how to get rid of this error. Thanks in advance.
