for i = 1:length(YON_BLNM)
Zi{i} = Z(BNdog==YON_BLNM(i),1);
end
I have to make 16 angles But I am having problems in the loop.

Please note that curly brace ({i}) makes a cell array and not a matrix. You have to use square brackets instead: []
So:
for i = 1:length(YON_BLNM)
Zi[i] = Z(BNdog==YON_BLNM(i),1);
end

"Error: File: dogrultu_kenar_hesabi.m Line: 302 Column: 7 Unbalanced or unexpected parenthesis or bracket."
This error occurs

@Muhendisleksi: This is a typo, obviously. Use Zi(i) instead with round parenthesis. Square brackets are the concatenation operator, see http://www.mathworks.com/matlabcentral/answers/35676-why-not-use-square-brackets .

Maybe so?
[~,ii] = ismember(BNdog,YON_BLNM)
Zi = Z(ii);

The question is the same question: https://www.mathworks.com/matlabcentral/answers/332101-i-can-not-create-a-matrix
"BNdog", "YON_BLNM", "ri" and "Z" are constantly changing. Do not we have a chance to write more dynamic?

Is not that possible?
