How to index input parameters?

Question

Hi,

I have a Matlab program that connects to a database and a server. I would like to make the server name and DB name to be dynamic such that the program can read them in from a flat file. Is there a sample code for that? Thanks,

Jennifer

I understand that you wish to read the database details from a text file and be able to index into it. Refer to the sample code below

fileID = fopen('scan1.dat');
C = textscan(fileID,'%s %s %f32 %d8 %u %f %f %s %f');
fclose(fileID);

In the above code, C{1}{1} has the first element. In your case if the first element is the database name,you can customize this code to read the entire file, and compare the first element with the database name you are trying to fetch using "strcmp". Once the comparison is successful, you can retrieve the rest of the elements in that row. Refer to the following documentation links on textscan and strcmp.
