    Graduate Need material to study Galois theory

    I would like to study Galois theory by myself (I've already studied group theory). Can anyone suggest any good video lecture or pdf available on the web? thank you in advance

    Graduate Matrix pseudo-inverse to do inverse discrete fourier transform

    Thanks for the reply. Unfortunately, the matrix M is usually: - rectangular because the number of space domain samples is different from frequency domain samples - badly conditioned

    Graduate Matrix pseudo-inverse to do inverse discrete fourier transform

    Hello, can anyone help me with the following problem: The discrete Fourier transform (DFT) in matrix form can be done as follows F=M*f where f are the space domain samples, F are the spatial frequency domain samples and M is the DFT matrix containing the exp(j*...) terms. To compute the...
