rms
Syntax
rms(X)
Arguments
X can be a numeric scalar, pair, vector, matrix, or table.
Details
Calculate the root mean square value of input X. Its formula is as follows:

Return Value
- If X is a scalar, pair, or vector, it returns a scalar.
- If X is a matrix, it returns a vector, with each element representing the RMS value of a column.
- If X is a table, it returns a single-row table, where each column contains the RMS value for that corresponding column.
Examples
Example 1: when X is a vector
X=[1,2,3,4,5]
rms(X)
// output: 3.317
Example 2: when X is a matix
X=matrix(1 2 3, 4 5 6)
rms(X)
// output: [2.160,5.066]
Example 3: when X is a table
X=1 2 3 4 5 6
Y=7 8 9 10 11 12
t=table(X as val1, Y as val2)
rms(t)
Output:
val1 | val2 |
---|---|
3.894 | 9.652 |
