Usage

For user input:

./matrix

For input file:

./matrix example.m

Phase 1

Features

• Dynamic creation and destruction of matrices of any size.
• Addition, subtraction, multiplication, transpose and division.
• Process input user commands and input file.

  Input sample

  A = [1.4 2.2 3.2; 4.4 5.4 6.4; 3.3 4.2 2.2];
  B = [1.5 4.1 5.4; 3.1 4.2 1.2; 3.2 4.3 2.2];
  C = A + B
  D = A - B
  E = A * B
  F = A / B
  G = A’

  Phase 2 (pending)

  Features

• Mathematical functions: Trigonometric, Logarithmic, Roots, Power
• Mathematical expressions: Either with (dot) or not.
• Flexible matrix parser: Accept matrix in matrix, expressions and variables
• Error handling: Do not crash for invalid input.

  Input sample

  A = 5.5 + 12 * sin(0.4) + 2.2^4;
  B = [1.2 2.3 A;[1.3 2.4;4.6 1.3],[3.2;7.8]];
  C = [[B [3.4; 2.1; 3.5+9.1]]
   1.2^3 3+1.2 15/(2.1+10*sin(0.12))  1.2]
  D = rand(4,4)
  E = eye(4, 4)
  F = zeros(2, 3)
  G = ones(3, 6)
  L = (1.2 + 3.4 - 5.6)/(2.1*3.2 + 4.6) - 12.1*3.1 + (1.2 + 5.2)^(4/(3.2+5.6))
  X = ((C*D .+ 4)./2.1 + sqrt(D))./C.^2
  Y = (C^3 * sin(1./D))^(0.1)
