@ctrendcoef |

Slope from a trend regression on each column of a matrix.

Syntax: @ctrendcoef(m)

m: matrix

Return: vector

Returns a vector of slopes from a trend regression, each the result of applying @trendcoef to the columns of m.

Examples

vector trend = @grid(0, 10000, 10001)

matrix m1 = @hcat(1+0.5*trend, 1+2*trend) + @mnrnd(10001, 2)

= @ctrendcoef(m1)

produces a vector of two elements, the first of which should be close to 0.5, the second of which should be approximately 2.
