Hey guys,

i have a problem to sort my files which i load with "dir".

i want to sort my list depending on three numbers.

my unsorted list looks like:

'dantec7100_Ma=01_wait_1000_ Yaw -10,00° Pitch -10,00°'

'dantec7100_Ma=01_wait_1000_ Yaw -10,00° Pitch -15,00°'

'dantec7100_Ma=02_wait_1000_ Yaw -10,00° Pitch -10,00°'

'dantec7100_Ma=02_wait_1000_ Yaw -10,00° Pitch -15,00°'

'dantec7100_Ma=01_wait_1000_ Yaw 10,00° Pitch 10,00°'

'dantec7100_Ma=01_wait_1000_ Yaw 10,00° Pitch 15,00°'

'dantec7100_Ma=02_wait_1000_ Yaw 10,00° Pitch 10,00°'

'dantec7100_Ma=02_wait_1000_ Yaw 10,00° Pitch 15,00°'

....

Ma goes from 01 to 07

Yaw goes from -20 to 20

Pitch goes from -20 to 20

I want the following sequence for all "Ma" starting from 01 to 07:

I want to start with "Ma=01". Then the lowest Yaw-Angle (-20) has to follow and to be fixed, and the pitch angles have to follow from the lowest to the highest (-20 to 20). Than increase the yaw angle to -5 and run again all pitch angle from -20 to 20, and so on for all yaw-angles. When this is ready, i want to increase "Ma" to 02 and do the same again.

i hope my problem is clear.

在 MATLAB Online 中打开

a = regexp(data,'.*Ma=0[1-7].*Yaw\s+0,00.*Pitch\s+0,00°$','match','once');
out = a(~cellfun(@isempty,a));

or

a = regexp(data,'(\-)?\d+(,\d+)?','match');
b = regexprep(cat(1,a{:}),',','.');
M = str2double(b(:,[2,4,5]));
out = data(ismember(M(:,1),1:7) & M(:,2) == 0 & M(:,3) == 0);
