# You asked: Is C row or column major?

Contents

## Does C use row-major or column major?

C uses row major, Fortran uses column. Both work. Use what’s standard in your programming language/environment.

## Is column row a major in Python?

The Python NumPy library is very general. It can use either row-major or column-major ordered arrays, but it defaults to row-major ordering.

## Is row-major or column major better?

In computing, row-major order and column-major order are methods for storing multidimensional arrays in linear storage such as random access memory. … In languages like Pascal and Fortran, iterating by column major order will be more efficient because 2-D arrays are stored in column major order there.

## Why is Matlab column major?

By default, MATLAB stores these elements with a column-major array layout. The elements of each column are contiguous in memory. N-dimensional arrays can also be stored in column-major or row-major layout. In column-major layout, the elements from the first (leftmost) dimension or index are contiguous in memory.

## Why is C row Major?

The C and C++ language specifications state that arrays are laid out in memory in a row-major order: the elements of the first row are laid out consecutively in memory, followed by the elements of the second row, and so on.

## What comes first row or column?

By convention, rows are listed first; and columns, second. Thus, we would say that the dimension (or order) of the above matrix is 3 x 4, meaning that it has 3 rows and 4 columns. Numbers that appear in the rows and columns of a matrix are called elements of the matrix.

## Is OpenGL row-major or column-major?

The OpenGL Specification and the OpenGL Reference Manual both use column-major notation. You can use any notation, as long as it’s clearly stated.

## Is row a major Java?

Consequently, Java is neither column-major nor row-major order (but see note below about how to read a[2][3] ), because while a given array’s entries are stored in a contiguous block of memory, the subordinate arrays those entries point to are object references to completely separate, unrelated blocks of memory.

## Why is Julia column major?

Probably because most numeric libraries were originally written in Fortran, which uses column-major storage, which then mimics the fact that vectors in math are by convention columns. Same applies to Matlab, which started as a convenient way to speak to some Fortran linear algebra packages.

## Is Matlab column or row first?

Indexing with Element Positions

The most common way is to explicitly specify the indices of the elements. For example, to access a single element of a matrix, specify the row number followed by the column number of the element.
