If a is a 3×3 matrix, the function of the function mean(a) is ( ).
A: to calculate the average of each row of a
B: to calculate the average of each column of a
C: to increase a row of the average for a
D: to increase a column of the average for a
A: to calculate the average of each row of a
B: to calculate the average of each column of a
C: to increase a row of the average for a
D: to increase a column of the average for a
举一反三
- If A is a matrix, the function of the function max(a(:)) is ( ). A: to work out the maximum element of the entire matrix B: function call errors C: to work out the maximum element of each row of the matrix D: to work out the maximum element of each column of the matrix
- If A is a matrix, the function max(A(:)) is ( ). A: to return the first element B: to return the maximum element in each row of the matrix C: to return the maximum element in each column of the matrix D: to return the largest element of the entire matrix
- Int(average(row(A1)+row(D6)))的结果为３。
- 14 In triple sequence table of sparse matrix, each triple represents ( ). A: the row number,column number and data value of non-zero elements in the matrix B: the data value of non-zero elements in the matrix C: the row and column numbers of elements in the matrix D: the row number,column number and data value of elements in the matrix
- Int(average(row(A1)+row(D6)))的结果为（）。 A: 1 B: 2 C: 3 D: 4
