Hello, I am trying to open a file with aprox. 1000000 lines and 3 columns, but I am having some problems to read the file. File format: -15.409204 ; -4.211755 ; 1.578635; ......
I used fscanf to read the file, but after debbuging it returns an empty array... seems to be related to a lack of memory, the code runs well in a computer with 8gb memory fid1 = fopen('vel1.txt','r'); vel = fscanf(fid1, '%f %f %f', [3 inf]); fclose(fid1);
To implement the algorithm that I want, I need to have the entire 3 arrays (each one corresponding to columns 1, 2 and 3), excluding the possibility to process the data by blocks. Is there other way to process this data, in a computer with less memory? Thank you
