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.

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')
