The external toolbox does not display enough parameters when setting the path. How to solve it?

>> LFToolboxPath = fileparts(mfilename('fullpath'));

fprintf('Adding paths for LF Toolbox ');

addpath( fullfile(LFToolboxPath) );

addpath( fullfile(LFToolboxPath, 'SupportFunctions') );

addpath( fullfile(LFToolboxPath, 'SupportFunctions', 'CameraCal') );

fprintf('%s, done.\n', LFToolboxVersion);

Adding paths for LF Toolbox ??? Error using ==> fullfile

Not enough input arguments.

?? Show us the outputs

[Huadong Hu]

does it have outputs?does it just add path?

[Walter Roberson]

Please show the output of

which -all fullfile

[Huadong Hu]

>> LFMatlabPathSetup -all fullfile

??? Error using ==> LFMatlabPathSetup

Too many input arguments.

[Walter Roberson]

I did not say LFmatlabPathSetup -all fullfile . I said

which -all fullfile

Here, "which" is the name of the command to execute.

[Huadong Hu]

I don't know where to find the name of the command to execute,I just want to run the LFmatlabPathSetup.M file.

[Walter Roberson]

At the MATLAB command line, type in the command

which -all fullfile

"which" is a literal command, just like "help" is a command.

If it helps you to understand, you could instead execute

which('-all', 'fullfile')

and if you have trouble understanding that, then execute

eval('which -all fullfile')

Do not replace the word "which" with anything else, put in the exact letters w h i c h (but with no spaces between them)

You are using MATLAB R14, from June 2004, a full decade before the Lightfield Toolbox https://www.mathworks.com/matlabcentral/fileexchange/49683-light-field-toolbox-v0-4 was released. It is likely you will encounter problems.

You could try changing the line

addpath( fullfile(LFToolboxPath) );

to

addpath( LFToolboxPath );

Do not change the remaining addpath() calls. I suspect that back then, fullfile() always expected at least two parameters.

[Huadong Hu]

followed your advice,it shows below,does it mean the problem is solved?

Adding paths for LF Toolbox Warning: Name is nonexistent or not a directory: SupportFunctions.

> In path at 115

In addpath at 95

Warning: Name is nonexistent or not a directory: SupportFunctions\CameraCal.

> In path at 115

In addpath at 95

v0.4 released 12-Feb-2015, done.
