sliding window for a sampled signal

I sampled a continuous signal by using rate transition block in Simulink. now, How can I calculate the maximum absolute value of previous i.e. 100 samples for each input sample. is there any simulink block? or should I use any digital filter and how?

When you have the signal as a vector, you can use movmean to find the moving average. You can modify the window to only include the previous 99 values to get a 100 value wide window.

M = movmean(A,[99 0]);

My signal is a time domain, not a vector. and I need the maximum value of previous 100 samples. I used the movmean and moving maximum blocks in simulink but they did not work and gives dimension error

I used movmax but the output is mxArray. how can I change to a double variable?

Perhaps you could use a Buffer Block with overlap specified.
