Help on txt file

Hello,

I am pretty new to Matlab, so excuse my bad understanding of its natural behaviour... :D

I want to create a txt file from my workspace, so I tried:

A = [38;70;102;134;166];
B = [10];
C =[10];   
D = [0];

Variablen = {'A =', 'B =', 'Umdrehungen =', 'C =', 'D = '};
Variablen_wert = [A;
                  B;
                  C;
                  D;];
log(2,:) = str2cell(Variablen_wert);
log(1,:) = Variablen;
fid = fopen('temp.txt','wt');
fprintf(fid,'%-4s  %d\n',log{:});
fclose(fid);

The obvious problem is, A is a matrix, while the other Variables dont have the same size. I tried to convert them into a string, but that doesnt work as well.

In the end it hopefully should look like this:

A = 38 70 102 134 166

B = 10

C = 10

D = 0

Maybe you can help me on this :) thank you very much

For me, the obvious problem is that you don't seem to pay much attention to the shape of the matrices in your desired output, so it's not clear what should happen if one of the variable happens to be a 2D matrix.

You write the A column vector as if it were a row vector. Isn't it a problem?

Unfortunately, that doesnt work neither... Tried both

I'm not sure who this is addressed to. I wasn't offering a solution ... yet, since as I've said the desired text output is not consistent with the input (printing a row vector, when the input is a column). Until you've clarified if the inconsensistency is on purpose, I'm not going to offer a solution that may not do what's needed.

Just make one combined cell, then use the function writecell().

Variablen_wert = {'A =' [38 70 102 134 166];'B =' [10];'C =' [10]};
writecell(Variablen_wert, 'temp.txt');

[AdamG2013468]

you can modify the second line,

writecell(Variablen_wert, 'temp.txt', Delimiter, ' ')

If you don't want to print the comma delimiters.
