How to read .params file via matlab?

Hello,

Does anybody knows how to read a .params file via matlab?

I have tried command fopen but it's no use?

Thank you

You mean this kind of .param file? That just looks like a plain text file. What would you want to do next with the data?

it's a kind of text data, but its .params file. To be honest I would like to read this file , like a txt file, and after that I would like to change one number from one specific line in this file

Reading text files to Matlab variables is one of the most commons tasks. One of the many, many functions is my readfile function, which is based on the internal fileread function (where my function also tries to account for the encoding, which is probably irrelevant in your case).

You can indeed use fopen, but you do actually need to use the functions with their intended use: fopen will generate a file identifier, which is a kind of handle that points to a specific file. You need it if you want to use fread or fprintf, two functions I would highly encourge you check out. Also note that every function documention page has a footer that contains links to several related functions that could be usefull.

Ok thank you first of all., My question is after reading this file How could I change one a specific line (let's say line 65) of the file in order to make it?

That depends on how you want to change it. You can either hardcode this change, or you need to find a way for Matlab to generate the required changed text.
