sortrows problem, i can't run my code file

Error using matlab.internal.math.sortrowsParseInputs>legacyParseCOL (line 106) Column sorting vector must contain integers with absolute value between 1 and the number of columns in the first argument.

Error in matlab.internal.math.sortrowsParseInputs (line 29) [col,colProvided] = legacyParseCOL(col,n,in2);

Error in sortrows (line 60) [col, nanflag, compareflag] = matlab.internal.math.sortrowsParseInputs(A,varargin{:});

Error in Final02 (line 37) Bigsize_sortcharactor=sortrows(Bigsize,11); >>

What can you tell us about Bigsize? Please describe the dimensions, the data type, etc.

Hi Geoff I have the same problem. My matrix is a 50000 x 2 matrix where the first column includes a dummy variable(either +1 or -1) and the second column includes small values between -2 and 2 (non integers as well). I want to sort the matrix according to column 2.

[Steven Lord]

Stef, please show your exact call to sortrows.

[Walter Roberson]

Your call to sortrows() is requesting sorting on column 11, but you only have two columns.

Answer 1

[Jos (10584)]

This replicates when the input to sortrows is not what you think it is.

A = [3 ; 1 ; 2] % 1 column only
sortrows(A, 2)  % -> errors as observed above

You could (should?) check the dimensions of A first using

size(A,2)

@Mathworks: why don't you make this error less cryptic by stating (more) explicitly that the first argument has less columns than the column sorting vector (especially when this is already a positive integer).
