too many input arguments

Im using prctile() to find the 70th percentile of 1300 elements, but matlab returns error too many input arguments. How can i fix this? Thanks

Show how your calling the function

[Elie Elias]

prctile(TM{:,7},70)

[madhan ravi]

size(TM{:,7})

Try the above and paste the result here

[Elie Elias]

it says Too many input arguments too but size (TM) returns 1315

[Elie Elias]

TM is a 1315x7 cell array

[madhan ravi]

Try

prctile(cell2mat(TM{:,7}),70)

[Elie Elias]

still too many arguments

[Elie Elias]

i tried to do

 v=zeros(size(TM,1),1);
 v=cell2mat(TM{:,7})

but it still says Too many input arguments

The first input to prctile must be numeric (double or single). So your cell array will need to be converted to numeric. You wrote that TM is a cell array, but you have not given us any description of how the data is arranged inside that cell array. This makes it hard to help you, as we have to guess.

If TM is a cell array that contains scalar numeric data in each cell of the seventh column, then try this:

prctile(cell2mat(TM(:,7)),70)

oh it works thanks but why does this work and not prctile(cell2mat(TM{:,7}),70)?

"oh it works thanks but why does this work and not prctile(cell2mat(TM{:,7}),70)?"

Because using curly braces creates a comma-separated list. Read these to know more:
