python to c

[ali.franco95]

Hi,

I know a little bit of python and am now starting to learn c. In python if I use numpy I have most things provided to me. For example If I want a sequence of 100 number between 1 and 10 I would just use numpy.linspace(1,10,100) . Now I know that I can quite easily do the same myself with a for loop, but I was wondering that it is something so often used would there be functions that do that for you in c. My other similar questions are that If I have two arrays and I want to append one to the end of the other is there a function in some library that does it.

Consider this 1,2,3,4,5,6,6.5,7,7.5,8,8.5,9,9.5,10,10.1,10.2,10. 3 ............. 14.9,15

The sequence from 1 to 15 is not equally spaced. Trivial to implement in python. I can do it in c with by defining a function and a for loop. Is C difficult because you have to do everything from scratch? Something like the sequence above is what I need very frequently it be annoying to write a code for it each time. If you know numerical libraries in C that do similar things as numpy please let me know. I am aware of gsl which is similar to scipy.

thanks guys.

So your complaint is that you have a library to do that for you in python, but that you have to rewrite it every time in C? Why don't you just write yourself a library of useful functions and call them when you need them? You know...just like you are doing in python with "numpy". Someone had to write that library for you to use.

I see that last sentence does sound like a complain, disregard it. I am more concerned about spending time on doing things that would have already been done by other people and because I am an amateur my version is most likely going to be less elegant/efficient. All I wanted was for some one to tell me, sorry son, you got to do it yourself. no easy meals in c.

Why aren't you looking for the C implementation? With a little luck, it'll already be done!
