numpy arrays are two-dimensional arrays, and not arrays of pointers. Make the following changes:
I am a newbie at coding. My sysyem is win10 64 bit. I'm using CodeBlocks to write C code. Also I'm using Python 3.10. This is my C code. This function adds the value 0.99 to all elements of a matrix. I want to call this function from python 3. My C file is;
ANSWERAnswered 2022-Apr-11 at 21:01
Requirements: With a C-function, 0.99 is to be added to all elements of a matrix. The matrix is to come from Python.
There are a couple of problems:
- the argument
sin the C function seems to be the intended Python matrix, but the parameter is not used at all in the C function.
- the type for
sis wrong, assuming a contiguous array it should just be
c_beshas no declared return type, you could use
voidsince the matrix elements can be manipulated in-place
- if you would prefer dynamically allocated memory on the C side after all, you should use the correct sizes, so if you want to work with a float array, you should not use
- if dynamic memory is used, you should also free it after use
- maybe use better naming to make the code more readable, e.g. something like
- with the compiler options
-Wall -Wextrayou get helpful warnings about possible problems in the code, use these
= 0.9assigns a fixed value, but actually you want to add something to the matrix element, so use the addition assignment
+= 0.99f. The
fat the end indicates that you want to work with a float constant and not a double constant
- in Python, the types of function arguments can be described using

using 'gatsby-plugin-dark-mode' in Typescript GatsbyWhat I did so far
- install 'gatsby-plugin-dark-mode' by
yarn add gatsby-plugin-dark-mode
- include 'gatsby-plugin-dark-mode' in gatsby-config.js

global.d.ts in the root of your project, and then add this:
declare module 'gatsby-plugin-dark-mode';
You can use this snippet for any package that throws that error and doesn't have published types.
