How to form this diagonal matrix?

E= diag [ 1  e^j*((2*pi)/M)........e^j*((2*pi)/M)*M-1 ]

where M=1024 and E= M x M diagonal matrix

[Janet]

pls share ur ideas

m = 4;
M = 1:m;
diagVals = exp(j*2*pi*(M-1./M))
E = diag(diagVals)

Is that right?

[Janet]

why is m=4?

[Jarrod Rivituso]

just because i didn't want a lot of output on my command window. you can easily change it to 1024 :)

thank u :)
