what is idct in matlab?
10946
x = idct( y ) returns the inverse discrete cosine transform of input array y . The output x has the same size as y . If y has more than one dimension, then idct operates along the first array dimension with size greater than 1.

Description. tf = isstrprop('str', ' category ') returns a logical array the same size as str containing logical 1 ( true ) where the elements of str belong to the specified category , and logical 0 ( false ) where they do not. The str input can be a character array, cell array, or any MATLAB numeric type.

In computing, ioctl (an abbreviation of input/output control) is a system call for device-specific input/output operations and other operations which cannot be expressed by regular system calls. It takes a parameter specifying a request code; the effect of a call depends completely on the request code.

A = imread(filename, fmt ) reads a greyscale or color image from the file specified by the string filename , where the string fmt specifies the format of the file. If the file is not in the current directory or in a directory in the MATLAB path, specify the full pathname of the location on your system.

Iddq testing. Iddq testing is a method for testing CMOS integrated circuits for the presence of manufacturing faults. It relies on measuring the supply current (Idd) in the quiescent state (when the circuit is not switching and inputs are held at static values). ... Typical Iddq tests may use 20 or so inputs.

A spatial transformation structure (called a TFORM struct) that can be used with the tformfwd , tforminv , fliptform , imtransform , or tformarray functions. T = maketform('affine', U,X ) creates a TFORM struct T for a two-dimensional affine transformation that maps each row of U to the corresponding row of X .

"idx" is usually short for index. Python loops allows items in a nested list to be accessed directly like so: >>> lst = [[1, 2], [3, 4], [5, 6]] >>> >>> for a,b in lst: print a,b 1 2 3 4 5 6.
