Supported CAS Operations Reference

Scalar Operations

Arithmetic: + - * / ^
Trigonometry: sin, cos, tan, asin, acos, atan
Log / Exp: log (natural), log10, exp
Other Math: pow(base, exp), sqrt, abs, ceil, floor, round
Constants: pi (3.14159), e (2.71828)
Matrix Properties: det(A), trace(A), norm(A), rank(A), min(A), max(A)

Vector & Matrix Operations

Linear Algebra: inv(A) (inverse), transpose(A), pinv(A) (pseudoinverse)
Decompositions: chol(A) (Cholesky), qr_q(A), qr_r(A) (QR), svd(A) (Singular values), eig(A) (Eigenvalues)
Echelon Form: rref(A) (Reduced Row Echelon Form)
Matrix Multiplication: A * B (standard matrix product when dimensions match)

Generator Functions

eye(n) — n x n identity matrix
zeros(m, n) — m x n zero matrix
ones(m, n) — m x n matrix of ones
linspace(start, end, n) — n linearly spaced points from start to end

Statistical Simulation

rand(m, [n]) — Uniform random matrix in [0, 1)
randn(m, [n]) — Normal distribution random matrix
randi(min, max, m, [n]) — Uniform integer random matrix
poisson(lambda, m, [n]) — Poisson distribution random matrix

Declaring Variables & Shapes

Scalar: s = 3.14159
Row Vector: r = [1 2 3] (space-separated)
Column Vector: c = [1, 2, 3] (comma-separated)
Matrix: M = [[1 2], [3 4]] (comma-separated row vectors)
Symbolic Function: expr f(x) = x^2 - sin(x)

Console & Workspace Commands

y = sin(x) — Evaluates and stores variable y
print(A) — Prints detailed matrix value or shape in console
plot(y) — Plots variable or function on interactive plot view
hist(r, 10) — Renders histogram of vector with 10 bins
clear — Clears all workspace variables and console history
remove name — Deletes variable by name
