Why the first number is not displayed? [SIMULINK]

Even if the variable block is connected to the workspace block the first value is not stored, why?

[Fangjun Jiang]

Note that the source block in the picture is FromWorkspace block, not a Constant block.

Thank you Fangjun noted with care :-)

Answer 1

[Fangjun Jiang]

For matrix formats, each row of the matrix has a time stamp in the first column and a vector containing the corresponding data sample in the subsequent column(s).

[madhan ravi]

Could you elaborate with a short illustration? Is it because the starting sample time is zero? Is there anyway to show the first element?

[Fangjun Jiang]

You are using FromWorkspace block and specify the data as a row vector (or 1xn matrix). By definition, the data in the first column is time. Try

x=[0.1, 1:10;]
