WebTools Used: ATMEGA2560, mbed online compiler, C++, J2EE. Summary: Developed an interconnected robot network which communicates between each other to reach a destination in a predefined path. WebFFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). We believe that FFTW, which is free software, should become the FFT library of choice for most ...
