Plots using multiple files

Greetings,
I am running the attached data with a .txt file runner (P3.m and Problem_4m)
The data runs and generates the numbers I want, the problem is how can I plot certain data.
For example for if you run Problem_4m it will generate the solutions for all my txt files (from P4_N1 - P4N200) and I need to plot
My N values go from N1, N5, N25, N50, N75, N100, N125, N150, N175, N200
the first plot is with N values and CL (these numbers are under workspace)
the second plot is with N values and CDi (these values are under workspace)
the third plot is N values with Gamma (These values are under workspace)
Is there a way to combine the results of ALL the .txt files into one single plot with the plots provided above

hello
I tried to run your code , but could you please clarify in which order you execute the tasks. it's not very clear
I also get error message from your code :
Right_Side.m Line: 52 Column: 1
??? Reference to non-existent field 'delta'.
On line 49 ==> DATA.CDi=((DATA.CL^2)./(pi*DATA.AR))*(1+DATA.delta);
last but not least, I don't understand your plot functions (P4_graph_CDi.m / P4_graph_CL.m / P4_graph_Gamma_y.m)
why do you have written a single numerical value for CDi , CL (must be alos a copy paste error there) and Gamma,
I was assuming that this would be vectors , computation results from your various functions - or where am I wrong ?
did you copy paste the values from the workspace ? why only one value appears ??

ok - so this is my suggestion for problem 4
there are for sure a more elegant way to manage file names and variables names together. Could be nice if you want to address various files names / quantities without having to do manual corrections in the code.
I tried to "streamline" a bit the process , so there is only one subfunction (exec2.m) and one main m file (Problem_4b.m)
still you have to manage the case with N= 1 , therefore no "delta" variable => error msg

@ Stephen , thank you for the link.... always good to look at the documentation from time to time.
@ Eddy - hum I can help you for debugging your code , but no, sorry, I am not here to do your home work
