I'm translating some code from Fortran77 to Matlab and I'm struggling due to the sentence GO TO is not valid in Matlab. Usually using sentences while I can solve the problem but in a particular case I don't know how to face it. To put in situation, i.e: code line 1 line 2 ... 128 a=a+1 if c==1 && kcount < 20 then line line if (h < 30) then go to 128 end if end if line line if (zmax == 0) go to 128 if (zmin. lt. 0.999d0*zmax) go to 128 line end The problem, if can be apreciated, is the go to inside the double if statement that also is in normal if statements. If it's neccesary I could write the code. Thanks!
