whose ith element is the size of the ith dimension. Items are undefined. Item Retrieve(A, i) ::= if (i ∈ index) return the item associated with index value i in array A else return error. Array Store(A, i, x) ::= if (i ∈ index) return an array that is identical to array...
matrix->col = col; matrix->elems = (Node **)calloc(row, sizeof(Node *)); return matrix; } void insertValue(SparseMatrix *matrix, int row, int col, int val) { // 向稀疏矩阵中插入非零元素 Node *newNode = (Node *)malloc(sizeof(Node)); ...
2-D, sparse, logical array C Syntax #include "matrix.h" mxArray *mxCreateSparseLogicalMatrix(mwSize m, mwSize n, mwSize nzmax); Arguments m Number of rows n Number of columns nzmax Number of elements that mxCreateSparseLogicalMatrix should allocate to hold the data. Set the value of ...
Matrix: 9 8 7 5 4 6 1 2 3 Sum of Main diagonal elements: 16 Sum of Opposite diagonal elements: 12 ExplanationHere, we created a 3X3 matrix matrix using the 2D array. Then we find the sum of main and opposite diagonal elements. After that, we printed the Matrix and the sum of...
