fgtp_engine · Vector addition: out

Read the equation

This relation defines Vector addition: out in the source section “fgtp_engine · Vector addition: out”. It specifies the displayed relationship between the named quantities or parameters. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

How it works

1. Read Vector addition: out as the quantity being defined or updated by this relation.

2. Substitute the source-defined variables or recorded values and follow the displayed arithmetic and indexing exactly.

3. Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.

Assumptions & limits

• This source expression was recovered from the pinned code revision. Its presence does not establish that the associated program was built, run, or scientifically validated.

Original context

    double sum = 0.0;
    for (size_t i = 0; i < size; ++i) {
        sum += a[i] * b[i];
    }
    return sum;
}

/// Vector addition: out = a + b
inline void vector_add(double* out, const double* a, const double* b, size_t size) noexcept {
    for (size_t i = 0; i < size; ++i) {
        out[i] = a[i] + b[i];
    }
}

/// Vector scalar multiply: out = a * scalar
inline void vector_scale(double* out, const double* a, double scalar, size_t size) noexcept {
    for (size_t i = 0; i < size; ++i) {
        out[i] = a[i] * scalar;

Vector addition: out = a + b
