mean
Average or mean value of arrays
M =
mean(A)
M = mean(A,dim)
M = mean(A)
returns the mean values of the elements along different dimensions of an array.
If A
is a vector, mean(A)
returns the mean value of A
.
If A
is a matrix, mean(A)
treats the columns of A
as vectors, returning a row vector of mean values.
If A
is a multidimensional array, mean(A)
treats the values along the first non-singleton dimension as vectors, returning an array of mean values.
M = mean(A,dim
)
returns the mean values for elements along the dimension of A
specified by scalar dim
.
A = [1 2 4 4; 3 4 6 6; 5 6 8 8; 5 6 8 8]; mean(A) ans = 3.5000 4.5000 6.5000 6.5000 mean(A,2) ans = 2.7500 4.7500 6.7500 6.7500
corrcoef
Correlation coefficients
cov
Covariance matrix
max
Maximum elements of an array
median
Median value of arrays
min
Minimum elements of an array
std
Standard deviation
