matlab在数学建模上的应用，包含数学建模常用算法以及历年建模题的代码(matlab application of mathematical modeling, including mathematical modeling commonly used algorithms and code for the theme of the calendar year modeling)

Root raised cosine filter implementation in matlab, with graphs of impulse and frequency response.

卷积运算：取x(t)和h(t)的长度为nx,nh。平移量n=nh+nx-1，利用for和if语句实现倒序求和运算。外循环用一个for语句实现平移，通过在求和时取数组元素的顺序实现倒序求和(Convolution operation: take x (t) and h (t) of length nx, nh. Translational volume n = nh+ Nx-1, use for and if statements to achieve reverse summation operator. Outside the circle with a for statement to achieve translation, when taken in sum array elements to achieve reverse the order of summation)

主成分分析和偏最小二乘SquaresPrincipal成分分析（ PCA ）和偏最小二乘（ PLS ） ，广泛应用于工具。此代码是为了显示他们的关系，通过非线性迭代偏最小二乘（ NIPALS ）算法。 (Principal Component Analysis and Partial Least SquaresPrincipal Component Analysis (PCA) and Partial Least Squares (PLS) are widely used tools. This code is to show their relationship through the Nonlinear Iterative PArtial Least Squares (NIPALS) algorithm. )
