3维压缩感知重构算法，采用最速下降法和梯度投影原理,逐步逼近最优解。是本人精心编写调试好的，请放心使用。-3 dimensional compressive sensing reconstruction algorithm, using the steepest descent method and the gradient projection principle, and gradually approaching the optimal solution.

梯度投影法GPSR的matlab源代码，可用于压缩感知的matlab仿真，将其中的camera图像替换就可直接运行其他图像，很方便-GPSR gradient projection method matlab source code can be used to compress perceived matlab simulation, which will replace the camera image can be directly run other images, it is conv
