Dot Product Function

vector<vector<float>> dotProduct (vector<vector<float>> inputs, vector<vector<float>> weights, vector<float> biases) {
    short col_count = inputs.size();
    vector<vector<float>> output (col_count);
    for(short i = 0; i < col_count; ++i){
        short row_count = inputs[i].size();
        output[i].resize(row_count);
        for(short k = 0; k < row_count; ++k){
            output[i][k] = inputs[i][k] * weights[i][k] + biases[i];
        }
    }
    return output;
