makeMat: Create a matrix of given size filled with a constant value

In cmpp: Direct Parametric Inference for the Cumulative Incidence Function in Competing Risks

Create a matrix of given size filled with a constant value

Description

This function creates an ⁠n x m⁠ matrix of type Eigen::MatrixXd, where each element is set to the specified constant value. This is useful for generating matrices with uniform values for testing, initialization, or other purposes in computational tasks where a matrix filled with a constant is needed.

Usage

makeMat(n, m, value)

Arguments

n	An integer representing the number of rows in the matrix.
m	An integer representing the number of columns in the matrix.
value	A numeric value that will be used to fill the matrix.

Details

The makeMat function generates a matrix with the given dimensions ⁠n x m⁠ where all elements are initialized to the same constant value. It is useful in scenarios where a specific value needs to be assigned to all elements of the matrix, for example in machine learning algorithms, matrix manipulations, or tests.

Value

A numeric matrix of dimensions ⁠n x m⁠ filled with the specified value.

Examples

library(cmpp)
# Create a 3x3 matrix filled with 5
mat <- makeMat(3, 3, 5)
print(mat)
