When you use From Workspace or From File to load arrays, then the first column is always interpreted as the timestamp. To avoid this you need to use the timeseries or struct input possibilities so you can supply the time information.

i am used time series and struct also but i am getting 1by4095 signal only,i am missing 1st element in 1st column..please check once

If you look at https://www.mathworks.com/help/simulink/slref/fromworkspace.html#btm3mv9-1 then notice it creates an extra column for the time. In your case since you have data for only one time, you could use 0 as the time.

As Walter said, you should use a separate column for the time. Please see this doc page for loading array data into the simulation using the "From Workspace" block: https://www.mathworks.com/help/simulink/ug/load-data-using-the-from-workspace-block.html#:~:text=Input%20Data.-,Load%20Array%20Data,-You%20can%20use

The issue is that you need 1 column of time values, and 1 column of data values for the simulator to behave as expected.

[Christoph Aistleitner]

If the values are constant and not time dependent, you could just use the Constant block.
