MImat2mat: Normalized Mutual Information Between Two Matrices

In conMItion: Conditional Mutual Information Estimation for Multi-Omics Data

Normalized Mutual Information Between Two Matrices

Description

Computes the normalized mutual information (MI) between corresponding rows of two matrices normalized by their individual information content, using the specified number of bins and spline order.

Usage

MImat2mat(mat1, mat2, bin = 6, sp_order = 2)

Arguments

mat1	A numeric matrix. For example, each row represents a gene and each column represents a sample.
mat2	Another numeric matrix to compare against. Must have the same dimensions as 'mat1'.
bin	An integer specifying the number of bins. Default is 6.
sp_order	An integer specifying the spline order. Must be less than 'bin'. Default is 2.

Value

A numeric vector where each element corresponds to the normalized mutual information (MI) between respective rows of 'mat1' and 'mat2'.

Examples

mat1 <- matrix(rnorm(10000), nrow = 100, ncol = 100)
mat2 <- matrix(rnorm(10000), nrow = 100, ncol = 100)
MImat2mat(mat1, mat2)
