Hi All,
I have a relative trivial question that I would be needing some guidence.
I have imported a data set called file22. The form of file22 is as follows:
If I want to access file22 Time column I type file22.Time, and the whole time column is selected..
I have multiple files:
file22,
file23,
file24 etc
What I am stuggling is to figure out a way where the user is prompted to type the file s/he wants to process, I have this but doesnt seem to work:
prompt = 'name of file : ';
FileName=input(prompt);
%conditioning tables for processing
%time stamp conditioning
FileName.Time=FileName.Time*60*60*24;
What I get is a table called file name.

Can you try to explain it more clearly, for example with inputs and expected outputs with some screenshots if possible?

Hi,
As mentioned in the question I have loaded into matlab several files:
file22
file23
file24
etc
Each file has been loaded as a table with 3 columns (Time,AMU,Pressure). If I whant to access the "'Time"column I write i.e file22.Time and Matlab will output the Time column of the table.
file22.Time
Since I have many files, as described before, I would like the script to ask the user what file it should handle:
prompt = 'name of file : ';
FileName=input(prompt);
hence ín this case if the user types file22, then
FileName.Time
Should read out the same table, instead though it creats the same file22 table under the name FileName
