I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article, let's take a look at it.

Matrix.

A matrix is a R object in which the elements are arranged in a two-dimensional rectangular layout, and they contain elements of the same atomic type. This data structure is very similar to two-dimensional arrays in other languages, but R provides language-level matrix operation support.

The elements in a matrix can be numbers, symbols, or mathematical expressions.

A M x N matrix is a rectangular array of M (row) row and N column (column) elements.

Matrix creation

The R language matrix can be created using the matrix () function, with the syntax format as follows:

Matrix (data = NA, nrow = 1, ncol = 1, byrow = FALSE,dimnames = NULL)

Parameter description:

Data vector, data of matrix

Number of nrow Lin

Number of ncol columns

Byrow logical value, arranged by column for FALSE and arranged by row for TRUE

Dimname sets the names of rows and columns

Create a number matrix. "

# byrow arranges M for TRUE elements by row
