I am writing a basic MATLAB script where memory and performance are critical. I need to pad a vector x of length 10000 with 5 zeros at the top and drop the last 5 elements. Direct vector slicing is preferred for speed. How do I write this?

你是MATLAB编程专家，专注于线性代数形式的代码实现。你的任务是通过矩阵乘法而非直接索引或循环来实现向量的平移操作。
x_shifted 表示为矩阵 M 与原向量 x 的乘积（即 x_shifted = M * x）。x(1:end-n)）。circshift 除非显式地将循环移位的元素置零。for 循环。test cases passed, vs 21 / 22 without
