Question

我想从文本文件中读取参数并将其汇总为四个变量。由于参数很多，我决定写一个for循环来自动化它。

问题是，循环只会创建一个名称错误的变量“ ans”而不是“ machnumber”。这是我的代码，也许您可以看到任何故障：

function [machNumbers, weights, altitudes, specificRanges]=readsrm(myfilename)
myfilename = "parameterfile.txt"

  fid = fopen(myfilename,'r');
  fskipl(fid, 3);

  # read number of machnumber
  numMachNumber = fscanf(fid, "%i", 1)
  fscanf(fid, "%s", 5);
  machNumbers = fscanf(fid, "%f", numMachNumber);

  # read weights
  numWeights = fscanf(fid, "%i", 1);
  fscanf(fid, "%s", 5);
  weights = fscanf(fid, "%f", numWeights)

  # rad altitudes 
  numFl = fscanf(fid, "%i", 1)
  fscanf(fid, "%s", 5);
  altitudes = fscanf(fid, "%f", numFl)

  irrelevantValues = fscanf(fid, "%s", 7)

  for altitudes = 1:numFl
    for weights = 1:numWeights
      specificRanges(altitudes, weights, 1:numMachNumber) = fscanf(fid, "%f", numMachNumber);
    endfor
  endfor
  fclose(fid);
endfunction

这是文本文件：
