    local result = {}
    for i = 1, #a do
    result[i] = {}
    for j = 1, #b[1] do
    result[i][j] = 0
    for k = 1, #a[1] do
    result[i][j] = result[i][j] + a[i][k] b[k][j]
    end
    end
    end
    return result
    end

    - HP-PPCM (HP Prime)
    A proprietary language combining elements of RPL (Reverse Polish Lisp) and Python, with hardware-accelerated functions for complex numbers and symbolic math.

    // Solve quadratic equation ax² + bx + c = 0
    PROGRAM "QUADRATIC"

    INPUT a, b, c
    disc := b² - 4ac
    IF disc < 0 THEN
    DISP "No real roots"
    ELSE
    x1 := (-b + √disc) / (2a)
    x2 := (-b - √disc) / (2a)
    DISP "Roots:", x1, x2
    END

    Key Considerations:

  • Memory Management: Stack-based languages (e.g., RPL) avoid dynamic allocation, reducing fragmentation.
  • Syntax Restrictions: Calculators often disable unsafe operations (e.g., `exec()` in Python) or require explicit declarations.
  • Hardware Integration: Direct access to calculator functions (e.g., `fnInt()` for integrals in TI-BASIC) bypasses general-purpose libraries.

    • Step-by-Step Guide to Writing a Custom Mathematical Function

    Developing a function in a programmable calculator involves defining variables, implementing iterative logic, and handling edge cases. Below is a structured approach using Python on HP Prime as an example:

    1. Variable Declaration and Initialization
    Define constants and variables with clear scopes. Calculator environments typically require explicit typing for performance.

    # Define constants
    PI = 3.141592653589793
    GRAVITY = 9.81 # m/s²

    # Initialize variables
    time = 0
    velocity = 0

    2. Loop Structures for Iterative Calculations
    Use `for` or `while` loops for repetitive operations, ensuring termination conditions prevent infinite execution.

    # Simulate projectile motion (time steps)
    max_time = 5 # seconds
    dt = 0.1 # time step
    for t in range(0, int(max_time/dt)):
    time += dt
    velocity += GRAVITY dt
    height = 0.5 GRAVITY time2 # Simplified
    print(f"Time: {time:.1f}s, Height: {height:.2f}m")

    3. Error Handling and Input Validation
    Implement checks for division by zero, invalid inputs, or overflow conditions. Calculators often lack exceptions, so use conditional blocks.

    def safe_divide(a, b):
    if b == 0:
    print("Error: Division by zero")
    return None
    return a / b

    # Example usage
    result = safe_divide(10, 0)

    4. Modular Design with Functions
    Break logic into reusable functions to improve readability and reusability.

    def newton_raphson(f, df, x0, tol=1e-6, max_iter=100):
    x = x0
    for _ in range(max_iter):
    fx = f(x)
    if abs(fx) < tol:
    return x
    dfx = df(x)
    if dfx == 0:
    print("Error: Derivative zero")
    return None
    x -= fx / dfx
    print("Warning: Max iterations reached")
    return x

    # Solve x² - 2 = 0
    root = newton_raphson(lambda x: x2 - 2, lambda x: 2*x, 1.0)
    print("Root:", root)
