Sin Cosine Tangent

Calculates the eigenvalues, state transition matrix, state vector and output of a linear system described in state space form.The answer is given in symbolic form.>> statespaceThe inputs A,B,C, and D must be given in matrix form.The input function or vector must be given in simple quotes.Ex:...

The function is much faster than Matlab's native (dct, idct, dct2, idct2). It also allows N-D (multidimensional) input.Example:x=randn(100,200,300);y=mirt_dctn(x); % forward DCTx=mirt_idctn(y); % inverse DCTFind more at my home page:http://www.bme.ogi.edu/~myronEnjoy and comment below if you like...

Y = DCTN(X) returns the discrete cosine transform (DCT) of X.X = IDCTN(Y) returns the inverse discrete cosine transform (IDCT) of Y.Y = DSTN(X) returns the discrete sine transform (DST) of X.X = IDSTN(Y) returns the inverse discrete sine transform (IDST) of Y.X and Y can be N-dimensional.D =...
