Simulink - From file block - Not defined time steps in .mat file (with examples)

I have file with a lot of data, for example here is a file with this data ->

time: 1 2 3 4 5 6 7 8 9 10
data: 1 0 1 1 1 1 1 0 1 0

but in my file I have dropped the multiple data going in sequence like this ->

time: 1 2 3 8 9 10
data: 1 0 1 0 1 0

If I run this data the result is this ->

My question is how to achieve result like in this picture shown with red arrows. Simplier, how to repeat the value in not defined time steps (4,5,6,7 example above)

Try: Double-click the "From File" block, then go to the option "Data extrapolation within time range:", and select "Zero order hold"

you can achive this by not droping the final (7 in this example) like this:

time: 1 2 3 7 8 9 10
data: 1 0 1 1 0 1 0

this way simulink will interpolate ones there.
