Matlab toolbox for parallel MRI data reconstruction with the Majorize-Minimize Memory Gradient Algorithm. This Matlab toolbox allows to solve the complex-valued image reconstruction problem arising in Parallel Magnetic Resonance Imaging (pMRI). The considered criterion is composed with a least square function as data fidelity term, and a regularization term favorizing the sparsity of the details coefficients of an orthogonal wavelet decomposition of the image. The reconstruction process uses the Majorize-Minimize Memory Gradient Algorithm described here:
