Errors when running matlab program

Hi

I am trying to run a program named TR1 version 4

It may be found at https://www.bracil.net/finance/Demos/Profiling/index.htm

I have left the input and output paths as is and am using the data provided

When I run the program, it asks for a threshold and I enter 0.001

Here is the ouput:-

*********************************************************************************************************

Please input the threshold (positive number): 0.001

Destination =

'C:\AnalysisResult\USDJPYmin(2016.07-2016.08)\'

Destination =

'C:\AnalysisResult\USDJPYmin(2016.07-2016.08)\'

Warning: Directory already exists.

> In TR1_4_Main (line 27)

Warning: The JavaFrame figure property will be removed in a future release. For more information, see Recommendations for Java and

ActiveX Users on mathworks.com.

> In TR1_4_Profile (line 115)

In TR1_4_Main (line 29)

Error using legend (line 279)

Invalid argument. Type 'help legend' for more information.

Error in TR1_4_Profile (line 117)

legend(Filename, 'Directional Change Events', 'Overshoot Events',2);

Error in TR1_4_Main (line 29)

[CPA DCA DCCstar time prices Filepath2] = TR1_4_Profile(name,Destination,Data,threshold); % for DC profile

********************************************************************************************************

I need help in understanding the various errors

Thank you

If you're talking about legend() - the built in one and not some custom one you wrote - I don't think it takes a filename. Try

legend('Directional Change Events', 'Overshoot Events');

If you've overwritten the built-in legend() with your own, then you'll have to debug that function.

To get rid of "Warning: Directory already exists." don't call mkdir() unless the folder does not exist.

if ~isfolder(Destination)
    % Only create destination folder if it does not already exist.
    mkdir(Destination);
end

Thank you.............

Understood and implemented mkdir problem

legend() - done !

Now the output:-

********************************************

Please input the threshold (positive number): 0.001

Destination =

'C:\AnalysisResult\USDJPYmin(2016.07-2016.08)\'

Destination =

'C:\AnalysisResult\USDJPYmin(2016.07-2016.08)\'

Unrecognized function or variable 'CPA'.

Error in TR1_4_Main (line 37)

for m=1:length(CPA)-1

Set a break point on that "for" line. Then look in the workspace at your variables. Do you see CPA listed? I think not. You need to define it.

I needed to mkdir twice (as it was originally)

Working now

Many thanks

Answer 4

Update: I now realize that of the two output files

(1) DC Data File has many output fields missing - should be 11 fields but only 5 currently shown

(2) Profile Summary File - perfect !

So, turning to TR1_4_sub_NDC.m, I notice many lines with "%" at the start i.e. commented out

I removed those which looked like they needed to be removed

Output now:-

**********************************************************************

Please input the threshold (positive number): 0.0075

Destination =

'C:\AnalysisResult\USDJPYmin(2016.07-2016.08)\'

Unrecognized function or variable 'Filepath2'.

Error in TR1_4_sub_NDC (line 246)

xlswrite(Filepath2,headers2,'sheet1','A1');

Error in TR1_4_Main (line 20)

[sub_CPA DCA time prices ] = TR1_4_sub_NDC(name,Destination,Data,sub_threshold*threshold); % for Sub_DC profile

************************************************************************

Any help on these error understandings ?

Once again you're using a variable without ever defining it. What do you think Filepath2 is? Evidently it was never defined, or at least never defined in a place that is "in scope" when you try to use it.
