Hello,

I am trying to interpolate data from a table in Simulink using the MATLAB function block. The data table is not time dependent, but I want the table to be read every time step.

I am using the From File block to load a .mat file that contains 3 columns. Column 1 and 2 are the X and Y input and Column 3 is the function result. At each time step I want to read X and Y from simulink, interpolate the 3d table, and output the function value.

When I load the table into my the MATLAB function block, only the third column is availible, since the function block assumes this is a time series with the first row being the time. But I want the whole table to be availible at any time step. I could hard code the table into the function or define three .mat input files, but neither of these are my preffered solution. Any advice would be appreciated.

Thanks
