Crate srmc

SRMC (Small Rust Math Crate)

srmc is a collection of mathematical methods, functions, and other useful tools. The goal is to make a stand alone math focused crate that can be used for a wide variety of applications. Will be continuously updated and improved as I imporve with the Rust langauge.

Structs

Matrix

SRMC Matrix struct with various implementations

Functions

create_identity_matrix

Returns an SRMC Matrix with diagonal values set to one.

create_matrix

Returns an SRMC Matrix swith provided dimensions. All elements of matrix are initially set to zero.

create_numbered_matrix

Returns an SRMC Matrix with provided dimensions. Elements of the matrix start at 1.0 and are incremented by 1.

create_sequential_vec

Creates a vector in numerical order from start to end with steps + 1 elements. NOTE: Elements of vector should be evenly spaced, but often times last two are not. Working on a fix for it, but if evenly spaced values is vital you may need to remove the final value or choose a different step size.

matrix_2x2det

Returns the determinant of a 2x2 Matrix.

matrix_3x3det

Returns the determinant of a 3x3 Matrix.

matrix_addition

Adds two Matricies together and returns the result as an SRMC Matrix

matrix_multiplication

Multiplies two Matricies together and returns the result as an SRMC Matrix.

matrix_subtraction

Subtracts two Matricies and returns the result as an SRMC Matrix.

matrix_transpose

Returns the tranpose of an SRMC Matrix

percentage_error

Function to calculate the percentage error between two values

relative_error

Function to calculate the relative error between two values

simpsons

Uses Simpson’s Method to evaluate a definite integral. Function to be integrated must take on parameter of type f32, and return a value of type f32. See the example functions (sin_x and x_cubed) for examples on how to format input.

sin_x

Example input function for sin(x)

trapzoidal_rule

Uses The Trapezoidal Rule to evaluate a definite integral. Function to be integrated must take on parameter of type f32, and return a value of type f32. See the example functions (sin_x and x_cubed) for examples on how to format input.

x_cubed

Example input function for x cubed
