    MATLAB What is the Expectation Value of (X'*X)^-1 in MATLAB for Signal Constellations?

    Hi, as I am new in Matlab, so I need your help. I want to replace the following inverse matrix (X'*X)^-1 with its expectation value: E{(X'*X)^-1} = E{|1/Xk|^2}I X'*X and (X'*X)^-1 is a diagonal matrix. Could anyone give me an Idea how to write it in MATLAB this expectation value...

    Understanding the Invariance of Hamming Distance: A Shift Proof

    Please help me ... to show that the Hamming disatance d(x,y) is invariant to a shift of both x and y i.e d(x+z, y+z)=d(x,y) Thanks a lot flo

    Is the set of integers Z={0,+-1,+-2, } .

    Thanks a lot, So the set of integers with operation of subtraction is not a group because the subtraction of integers is not associative.So a-(b-c) is not equal to (a-b)-c. Thanks a lot, florent

    Is the set of integers Z={0,+-1,+-2, } .

    Is the set of integers Z={0,+-1,+-2,...}... Hi, Can anybody help me. I know that integers under Addition is a group, but Is the set of Integers Z={0,+-1,+-2,...} together with the operation of subtraction a (noncommutative) group. Thanks a lot Flor
