Instead of global p1, p2, p3, and so on, and the if/elseif chain, why not just global Pvals and set Pvals{i} = p; ?

[Jan]

Note: This:

s = cell_vectorname{1,indexMin}

is nicer and faster than:

s = cell2mat(cell_vectorname(1,indexMin))

Instead of using p1, p2, ...p10, a vector p(1:10) would be more efficient and easier to handle.

You have not given us any reason to expect that cell_rMatrix is a row vector containing at least 10 elements. It might be a column vector instead, or it might have fewer elements. After you do the load() operation, you should display

size(cell_rMatrix)

to see what size it really is.

[anju]

it is a row vector where each cell contains a wave file. Each wave file contains 50 words.. it works for a wave file with 2 words.. but not for the above. please do help.

and the size is 1x4.

[Walter Roberson]

So it is 1 x 4, but you have "for i=1:10" so you are going to try to access up to 1 x 10 and that will fail as soon as "i" hits 5.

Perhaps you should be coding

for i = 1 : length(cell_rMatrix)

[anju]

still the code is not giving the output.. for 2 words the NilaiMin value is displayed on the screen.. but for 50 words its not displaying NilaiMin .. NilaiMin gives the global minimum value which is output from dtw algorithm..

[anju]

in our .m file its showing that it has no output arguments.. what does it indicate???
