Sort row by descending error

Hi. I have a cell like this.

A=

     'Q7'      [ 0]
     'Q12H'    [-3]
     'Q12G'    [ 0]

I want to sort by descending direction.

But it says that amaxfc=sortrows(amaxfc,2,'descend');

it says that

Error using sortrows
Too many input arguments.

The 'descend' option was not added until R2013b. Use

amaxfc = sortrows(amaxfc, -2);

Answer 2

[Star Strider]

Try this:

A = {'Q7'     [ 0]
    'Q12H'    [-3]
    'Q12G'    [ 0]};

amaxfc=sortrows(A,2,'descend')

amaxfc =

    3×2 cell array

      'Q7'      [ 0]
      'Q12G'    [ 0]
      'Q12H'    [-3]

I had the same problem as the OP, using 2016b. I am pretty sure that it worked earlier (I have been using that code for a while without touching it). Unfortunately your example does not work either. Walter Robertson's legacy work around does, however. Strange.

same here on 2016b I get this error

 [a,b]=sortrows(data,2,'descend')

 Error using sortrows
 Too many input arguments.

[Star Strider]

I no longer have access to R2016b, so I can’t experiment with it.

Do you have a different variable or function called ‘sortrows’?

See what:

which sortrows -all

reveals.

According to the documentation of sortrows in R2016b, I see only numerical arrays, CHAR matrices and tables as input, but not cell arrays. But the code works for cells also.

According to the help text and the source code, there are 2 inputs only in R2016b. Therefore the error message is expected and clear.

The 3rd input works only in R2016b, if you apply sortrows to a table object.
