Excellent answers. I can't thank you all enough! As I say, I'm new to the FORTRAN business but everyone has been perfectly explanatory and helpful.
I'll have to come back here more often :)
Thanks for the answer, qsal. Very informative.
Although I do then have a couple of follow up questions.
I'm assuming that if you don't declare a variable ahead of time, the variable does still need to be declared somewhere in the program? Would FORTRAN77 throw up an error if you did not do...
Hi all
Just to start with I should highlight my general ineptitude with programming, so I apologize if my question is totally basic.
I have a program written (by someone else) in fortran 77. Contained within it is a call to a function which acts on a number of variables. My curiosity is about...
Differenciating Sin and Cos is very easy. (It gets trickier with the more complicated trig functions, like Tan). The way I like to remember it, is as follows:
Sin(x)
Cos(x)
-Sin(x)
-Cos(x)
When you differenciate one of these functions, you simply move down the tower to the next function. When...
