y=dst(x) x=idst(y)
Description
y=dst(x)
computes the discrete sine transform of the columns of x. For best performance speed, the number of rows in x should be 2m - 1, for some integer m.
y=dst(x,n)
pads or truncates the vector x to length n before transforming.
If x is a matrix, the dst operation is applied to each column.
x=idst(y)
calculates the inverse discrete sine transform of the columns of y. For best performance speed, the number of rows in y should be 2m - 1, for some integer m.
x=idst(y,n)
pads or truncates the vector y to length n before transforming.
If y is a matrix, the idst operation is applied to each column.
