Hello all, hope you having a great day. I am trying to import the file filled with exponential numbers. Is there a function to import such data or do I need to put proper data spec to read the file? I attached the file fyi. Below is just the part of the file.

The file you attached is empty.
If you use split on this text you can use str2double to read this list to a Matlab array.

All of MATLAB's standard file importing functions correctly parse exponent notation. What have you tried so far?

I just noticed that the file becomes empty when I zip it. I changed the format to .txt from .d.
I have tried fread, fscanf and importdata. To read exponent notation, how should the format spec look like?

You are making this far more complex than it needs to be:
M = readmatrix('1.txt')
M = 1656×6

Thank you for the answer. The extension of the original file is .d, so readmatrix doesn't work, but I think I could read the file by using textscan with proper format.

Specify the filetype:
M = readmatrix('1.d', 'FileType','text')
