MATRIX—END MATRIX 929
CMAX(M) Column maxima. Takes a single argument. Returns a row vector with
the same number of columns as the argument. Each column of the
result contains the maximum value of the corresponding column of the
argument.
CMIN(M) Column minima. Takes a single argument. Returns a row vector with
the same number of columns as the argument. Each column of the
result contains the minimum value of the corresponding column of the
argument.
COS(M) Cosines. Takes a single argument. Returns a matrix having the same
dimensions as the argument, containing the cosines of the elements of
the argument. Elements of the argument matrix are assumed to be
measured in radians. To convert degrees to radians, multiply by π ⁄ 180 ,
which you can compute as ARTAN( 1)
⁄ 45 . For example, the statement
COMPUTE COSINES=COS(DEGREES*ARTAN(1)/45) returns
cosines from a matrix containing elements measured in degrees.
CSSQ(M) Column sums of squares. Takes a single argument. Returns a row
vector with the same number of columns as the argument. Each
column of the result contains the sum of the squared values of the
elements in the corresponding column of the argument.
CSUM(M) Column sums. Takes a single argument. Returns a row vector with the
same number of columns as the argument. Each column of the result
contains the sum of the elements in the corresponding column of the
argument.
DESIGN(M) Main-effects design matrix from the columns of a matrix. Takes a
single argument. Returns a matrix having the same number of rows as
the argument, and as many columns as the sum of the numbers of
unique values in each column of the argument. Constant columns in the
argument are skipped with a warning message. The result contains 1 in
the row(s) where the value in question occurs in the argument and 0
otherwise. For example, if:
128
138
A =
265
338
365
, then: DESIGN( A)
=
10010010
10001010
01000101
00101010
00100101
The first three columns of the result correspond to the three distinct
values 1, 2, and 3 in the first column of A; the fourth through sixth
columns of the result correspond to the three distinct values 2, 3, and 6
in the second column of A; and the last two columns of the result correspond
to the two distinct values 8 and 5 in the third column of A.
