将for循环生成的矢量长度不同的输出值保存/追加到MATLAB中的单独文件中 [英] Saving/appending output values of varying vector length generated from for loop into separate files in MATLAB

问题描述

在迭代保存或附加通过for循环内的函数生成的"dist"和"P"获得的输出时，我需要帮助.虽然显示了输出，但是我无法将"dist"和"P"中的各种输出值保存在单独的文件中 没有覆盖.

I need help in iteratively saving or appending the output obtained in terms of "dist" and "P" generated through a function inside a for loop. Although, the output is displayed I am unable to save the various output values from "dist" and "P" in separate files without overwriting.

输入数据在两个Excel文件中提供

The input data is provide in two excel files

Test1.xlsx
26
50
52
56
58
59
77
78
79
80

Test2.xlsx
51
52
187
188
189
191
226
227
228
229

我使用的邻接矩阵是adj.xlsx

and the adjacency matrix I used is adj.xlsx

我正在使用的matlab代码如下:

The matlab code I was using is as below:

adj=xlsread('adjmat.xlsx','Sheet1','A1:JO275')
SP1=xlsread('Test1.xlsx','Sheet1','A1:A10');
INHBP=xlsread('Test2.xlsx','Sheet1','A1:A10');
for i=1:length(SP1)
for j=1:length(INHBP)
[dist,P]=dijkstra(adj,SP1(i),INHBP(j))
end
end

在matlab工作区中显示的示例输出如下:

The sample output displayed in the matlab workspace is a below:

dist =
    27
P =
    26    38    40    50    51
dist =
    27
P =
    26    38    40    50    52
dist =
    78
P =
    26    38    40    50    52    55    60    63    80    82   116   117   119   187
dist =
    88
P =
    26    38    40    50    52    55    60    63    80    82   116   117   119   187   188
dist =
    98
P =
  Columns 1 through 15
    26    38    40    50    52    55    60    63    80    82   116   117   119   187   188
  Column 16
   189
dist =
    73
P =
    26    38    40    70    71    75    76   108   111   113   136   175   178   180   191
dist =
    85
P =
    26    38    40    50    52    55    60    63    80    82   116   117   118   198   226
dist =
    44
P =
    26    38    40    50    52    55    60    63    83   227
dist =
    33
P =
    26    38    40    50    52    55    60    63   166   228

但是我希望将结果保存在dist和P的单独文件中(结果是向量长度的变化)

But I want the results to be save in separate files for dist and P (results are varying length of vectors), for instance

dist =
    27
    27
    78
    88
    98
    73
    85
    44
    33


P =
    26    38    40    50    51
    26    38    40    50    52
    26    38    40    50    52    55    60    63    80    82   116   117   119   187
    26    38    40    50    52    55    60    63    80    82   116   117   119   187   188
    26    38    40    50    52    55    60    63    80    82   116   117   119   187   188   189
    26    38    40    70    71    75    76   108   111   113   136   175   178   180   191
    26    38    40    50    52    55    60    63    80    82   116   117   118   198   226
    26    38    40    50    52    55    60    63    83   227
    26    38    40    50    52    55    60    63   166   228

推荐答案

您可以使用fopen创建txt对象，然后使用fprintf在此文本文件中写入:

You can use fopen to create your txt object and then write in this text file with fprintf:

fid1 = fopen('dist.txt','w');
fid2 = fopen('P.txt','w');

adj=xlsread('adjmat.xlsx','Sheet1','A1:JO275')
SP1=xlsread('Test1.xlsx','Sheet1','A1:A10');
INHBP=xlsread('Test2.xlsx','Sheet1','A1:A10');
for i=1:length(SP1)
for j=1:length(INHBP)

[dist,P]=dijkstra(adj,SP1(i),INHBP(j))
    b = sprintf('%d ',P);
    fprintf(fid1,'%d\n',dist)
    fprintf(fid2,'%s\n',b)
end
end

fclose(fid1);
fclose(fid2);
