Matlab Eingine does not react (c++)
Good morning Matlabbers! I have recently started working with Matlab. To get familiar with the Matlab Engine and its functions I have created a simple c++ programm, which puts some variables into the engine and evaluates some strings. Everythings works perfectly. Afterwards I have started to add these functions t... 10 Jun 2010 07:46

how to add missing dates

Replace Negative values with Non-zero values
Dear kev! What I want is something like... x(x<0)=x+360; x(x < 0) = x(x < 0) + 360; or with temp array, which is perhaps faster: lt_zero = (x < 0); x(lt_zero) = x(lt_zero) + 360; Jan ... 10 Jun 2010 07:46
