说明：  用函数bwtraceboundary进行边界跟踪(Use function bwtraceboundary to trace the object boundary)

the decoding of Huffman codes is shown. For the decoding the coding tree has to be constructed using the information which has to be transmitted as well. Following that the input is read bitwise and for each 0 a left turn is taken and for each one a right turn until a leave is reached. In this case the value of the leave (usually a character) is output, continuing after that at the root.

Fixed-Point iteration(Function fixed_point(p0, N) approximates the solution of an equation f(x) = 0, rewritten in the form x = g(x), which is a sub-function the user has to enter. the call to the function fixed_point(p0, N) returns the root of the equation f(x),i.e. the fixed-point of g(x), if the procedure is successful or a sequence of iterates in case something goes wrong. p0 is the initial approximation and N the maximum number of iterations. If, after N iterations, condition |x(k)- x(k-1)| < tol is not satisfied, all iterated values will be displayed, accompanied by a message asking the user to either change p0 in case of divergence or enter another g(x) that does not lead to complex numbers arithmetics. Reasons for the program to go wrong are the divergence of iterates and/or appearance of complex numbers for example with functions involving sqrt(x) when one of the iterates is negative. )

use a three order loop to track the GPS L2C signal, could be useful for beginner
