Webis how one would use Fortran to create arrays from the even and odd entries of an array. Another common use of vectorized indices is a filtering operation. Consider a clipping operation of a sine wave where amplitudes larger than 0.5 are to be set to 0.5. Using S-Lang, this can be done by y = sin (x); y [where (abs (y)>0.5)] = 0.5; WebFeb 23, 2013 · Python follows EWD's recommendation exactly. It start at 0, and the ending index does not include the element. Example: Python's way is the most painful to work with.

WebThis Fortran 90 function returns the index of the element in the array, whose value is minimum. If c(1)=1, c(2)=0, and c(3)= -1, then "minloc(c(1:3))" returns the integer "3". Due to requirements for use with multidimensional arrays, the value of this function must be returned to an array. WebFortran and C arrays differ in two ways: The value of the lower array bound is different. By default, Fortran indexes the first element of an array as 1. C and C++ index it as 0. Fortran subscripts should therefore be one higher. (Fortran also provides the option of specifying another integer lower bound.)
