Cosine Definite Integral

This calculator computes definite integrals by tinh-sinh quadrature scheme. Type formula into Integrand text-box. Change default values of lower and upper limits of integration. Click Calculate button. Watch if the algorithm is converging. The Current Uncertainty value should be steadily...

Q = MULTIQUAD(F,S) approximates the S-dimensional integral of a function F(X) over the unit cube, with 3

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...
