Hello,

i wrote an algorithmn in matlab to analyse data from excel. There just the time and the velocity which is a measurement from a sensor.

Now i want to apply the algorithmn on just 50 data points from the big data sheet. After that (maybe after 1 sec) the next 50 data points should be analysed with the algorithm and so on. The result should be somewhere saved and will be always added with the new result.

I think i can use the algorithmn in simulink with a matlab function block.

Unfortunately i do not know how i can simulate an continuous data input.

Thank you for help!

What I understood from is that you would like to gradually read-in data to an algorithm.

One way to read data into Simulink is with a From Spreadsheet block. Below is a link with more information about this block:

Once the data has been read into Simulink, it is possible to use a Buffer block in order to store it. Below is a link with more information about this block:

The Buffer block will store data up to a fixed limit. Once that limit is reached, that data will all be released simultaneously.
