I have a question if it's possible to make a specific code shorter, i.e I'm looking for a way to simplify the code.

Now the code looks like this:


load splitmu_no_steerback_mna50kph_1_200kpa
Test_Plot_SteerAngle_Speed
plot (sync_Var_SA(:,1), sync_Var_SA(:,2))
hold on
plot (sync_Var_VS(:,1), sync_Var_VS(:,2))

load splitmu_no_steerback_mna50kph_2_200kpa
Test_Plot_SteerAngle_Speed
plot (sync_Var_SA(:,1), sync_Var_SA(:,2), 'r')
hold on
plot (sync_Var_VS(:,1), sync_Var_VS(:,2), 'r')

load splitmu_nosteerback_mna50kph_1_igen.mat
Test_Plot_SteerAngle_Speed
plot (sync_Var_SA(:,1), sync_Var_SA(:,2), 'g')
hold on
plot (sync_Var_VS(:,1), sync_Var_VS(:,2), 'g')

load splitmu_nosteerback_ugr50kph_1_200kpa
Test_Plot_SteerAngle_Speed
plot (sync_Var_SA(:,1), sync_Var_SA(:,2), 'y')
hold on
plot (sync_Var_VS(:,1), sync_Var_VS(:,2), 'y')


This shows 4 files being processed, but there will be more files.

It's the same processing of data in "Test_Plot_SteerAngle_Speed",
and the same variables are plotted, only with data from different files.

Is there a way to make some kind of loop that loads a file, then process the data and then makes the plot. Then loads a new file, process the data and makes the plot in a different color from the previous one. The different curves must be in the same plot.

Well, I guess that didn't help me in my problem...

The files can't have the same name and just be sequentially numbered.

And the second part that said: "If instead you want to process all the files whose name matches a pattern in a directory, you can use DIR to select the files:"

But it uses the command "imread" which works just for pictures, right?

There's no reason to not use the filenames returned for whatever purpose
you want; there's nothing magic about imread(); it could just as easily
be fopen() or the filename passed to textscan() or whatever...

Live a little...be creative and expand on a theme!!! (Even read the
veryfinemanual and examples if all else fails... :) )

I just clarified that section of that FAQ entry.
