编译时出现以下错误:错误:数组下标 interactionMatrix[i][k]=interaction;

代码如下:

void Tree::computeInteractionScore(size_t* interactionMatrix){
size_t num_independent_variables = data->getNumCols() - no_split_variables->size();

for (size_t i = 0; i < num_independent_variables; ++i) {
for (size_t k = 0; i < num_independent_variables; ++k) {
size_t interaction = 0;
if(k!=i){
// interaction = computeInteraction(i,k);
}
interactionMatrix[i][k]=interaction;
}
}
}

interactionMatrix 声明如下:

  size_t num_independent_variables = data->getNumCols() - no_split_variables->size();

size_t interactionMatrix[num_independent_variables][num_independent_variables];

for (size_t i = 0; i < num_trees; ++i) {
trees[i]->computeInteractionScore(&interactionMatrix);
}
