Subtraction
C = A - BC = minus(A,B)Create an array, A, and subtract a scalar value from it.
A = [2 1; 3 5]; C = A - 2
C =
0 -1
1 3
The scalar is subtracted from each entry of A.
Create two arrays, A and B, and subtract the second, B, from the first, A.
A = [1 0; 2 4]; B = [5 9; 2 1]; C = A - B
C =
-4 -9
0 3
The elements of B are subtracted from the corresponding elements of A.
Use the syntax -C to negate the elements of C.
-C
ans =
4 9
0 -3
Create a matrix, A. Scale the elements in each column by subtracting the mean.
A = [1 9 3; 2 7 8]
A =
1 9 3
2 7 8
A - mean(A)
ans =
-0.5000 1.0000 -2.5000
0.5000 -1.0000 2.5000
A — Input arrayInput array, specified as a scalar, vector, matrix, or multidimensional
array. Numeric inputs A and B must
either be the same size or have sizes that are compatible (for example, A is
an M-by-N matrix and B is
a scalar or 1-by-N row vector).
For more information, see Compatible Array Sizes for Basic Operations.
Datetime, duration, and calendar duration arrays must be the same size unless one is a scalar. If one input is a datetime array, duration array, or calendar duration array, then numeric values in the other input are treated as a number of 24-hour days. If one input is a datetime array, then the other input also can be a date string or a cell array containing date strings.
Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | char | datetime | duration | calendarDuration
Complex Number Support: Yes
