Please help with my function that is to read files.

 function readd(txxt)

 data = dlmread(txxt, '', 43, 0);
 mass = data(:, 3);
 temp = data(:, 2);
 time = data(:, 1);

 end

This is what it returns in the cmd window:

Not enough input arguments.

Error in untitled7 (line 4) data = dlmread(txxt, '', 43, 0);

I've tried setting the left hand side of the function equal to: [data] [mass,temp,time]

Nothing worked.

Guessing here, but '' is an empty string. If you want to specify a space, put a space between the quotes.

See if this works:

data = dlmread(txxt, ' ', 43, 0);

That part is not a problem. I can actually read the text file just fine with that original line of code. The problem is I can't seem to have it as a function.

You cannot run a function by simply clicking ‘run’. You have to use it in a command:

txxt = 'file.txt';
readd(txxt)

Of course it is not going to return anything to your workspace. To do that, you need to specify it as:

function [mass,temp,time] = readd(txxt)

then call it as:

txxt = 'file.txt';
[mass,temp,time] = readd(txxt);
