I have this text file.

I want to use store this in a variable and use it in sprintf(variable, 1e3, 1e3, 1.5e6) format in MATLAB.
Thank you in advance.

Terribly sorry.
As far as I know there is no suitable function for reading a file and extract data from such variable positions. I think you will have to read the file (either line by line or the full file) and then process it line-by-line and process each line according to its content and your knowledge about the forma of each line. Will you have the lines in the same order then your work is a bit simpler, but in my experience some files will have the lines in some permuted order. My suggestion is that you make a function for reading these files, and put a subfunction for parsing out the data from each type of line - that way you at least have some structure in the programme.
