findstringline

Function finds the lines that a given string is present in a text file.

I often have to import large data sets broken into chunks within a text file. Each data chunk has a header at its beginning. To identify the lines at which I need to begin importing data, I wrote this code.

So given a data chunk header, say str = 'Event #', this code will return to you every line that the header 'str' is present within. This aids in using the function textscan to import the data chunks. I simply use the line numbers found in this function as the 'SkipLines' for the textscan function.
