Python——Excel数据转化为矩阵

def excel2m(path):
    data = xlrd.open_workbook(path)
    table = data.sheets()[0]
    nrows = table.nrows  # 行数
    ncols = table.ncols  # 列数
    c1 = np.arange(0, nrows, 1)
    datamatrix = np.zeros((nrows, ncols))
    for x in range(ncols):
        cols = table.col_values(x)
        minVals = min(cols)
        maxVals = max(cols)
        cols1 = np.matrix(cols)  # 把list转换为矩阵进行矩阵操作
        ranges = maxVals - minVals
        b = cols1 - minVals
        normcols = b / ranges  # 数据进行归一化处理
        datamatrix[:, x] = cols1  # 把数据进行存储
