If detA=0, thenAmust have a row or column of zeroes.
举一反三
- In a spreadsheet, a cell is defined as the A: intersection of a table and a row B: intersection of a table and a column C: intersection of a row and column D: intersection of a column and a record
- 若detA=0,证明detA*=0
- 阅读下面程序： #include ＜iostream.h＞ void main() int i,j,row=0,column=0,m; static int a[3][3]= 100,28,72,-30,2,-100; m=a[0][0]; for(i=0;i＜3;i++) for(j=0;j＜3;j++) if (a[i][j]＜m) m=a[i][j]; row=i; column=j; cout＜＜m＜＜","＜＜row＜＜","＜＜column＜＜endl; 该程序的功能是______，其执行结果为______。[/i][/i]
- HBase的物理结构为row，column family，column，timestamp :value。
- 下列等式成立的是()。 A: COLUMN(A23)=1 B: COLUMN(W23)=23 C: ROW(A23)=1 D: ROW(W23)=23
