mean

mean(X)

Calculate the average of X.

• If X is a matrix, calculate the average of each column and return a vector.

• If X is a table, calculate the average of each column and return a table.

This function is equivalent to avg.

The calculation skips null values.

X is a scalar/vector/matrix/table.

• If X is a vector, returns a DOUBLE scalar.

• If X is a matrix, returns a DOUBLE vector.

• If X is a table, returns a table.

x=1 5 9;
mean(x);
// output: 5

x=1 5 9 NULL;
mean(x);
// output: 5

avg(x);
// output: 5

m=matrix(1 2 3, 4 5 6);
m;

mean(m);
// output: [2,5]
