Removes a trend from input data.

## Syntax

y = detrend(x)
y = detrend(x, option)
y = detrend(x, option, break)

## x

Data from which you want to remove a trend. x is a vector or matrix. If x is a matrix, MathScript performs column-wise detrending.

## option

Trend to remove from x. option is a string that accepts the following values:

Name Description
'constant'

Removes mean values.

'linear'

Removes linear effects where the breakpoints are defined by break.

Default: 'linear'

## break

Specifies the breakpoints. break is a vector of indexes of x. If you specify the 'constant' trend, you cannot specify break.

## y

x with the trend removed.

X = [3, 2, -1; 1, 6, 3; 2, -4, 0];
Y = detrend(X)
