举一反三
- 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
- 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 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
- Let A be a [img=40x20]1803c4e60908a8b.png[/img]matrix, and the determinant of A is 0,then _________. A: there must be a column of elements in A that are all 0 B: there must be a column in A that is a linear combination of the other column vectors C: there must be two columns that are proportional to each other D: any column vector in A is a linear combination of the remaining column vectors
- In the periodic table of elements, the number of elements in each period is exactly equal to the maximum number of electrons in the corresponding outermost electron layer.
