Dear all
I am extracting from a file in a for loop information in the following form: ' ( 0.0357 -0.0001 0.0051) ', which is a 1x27 char. I would like to store the three displayed numbers in a the three components of an array so I can use these figures to do mathematical operations. How could I transform them to do so in this case, keeping the minus signs that can appear for different steps of the for loop too?

Hi Richard,
To extract the numbers from the string and store them in an array, you can use the "sscanf" function
Here's how you can do it:
% Example string
str = ' ( 0.0357 -0.0001 0.0051) ';
% Use sscanf to extract the numbers
numbers = sscanf(str, ' ( %f %f %f) ');
disp(numbers);
Please refer to the below MathWorks documentation link:
Hope this helps!
