Error: Brace indexing is not supported for variables of this type.

Hi there,

I am trying to convert a cell into a vector, but I always get the error message: "Brace indexing is not supported for variables of this type."

% Datum korrigieren (date originally is a 14386x1 cell)
date(1,:)=[] ;                          % remove word 
row1 = cell2mat(date(1,:));             % Start time
datenum= str2double(date);
datevec = cell2mat(datenum{:});         % cell to vector
                                        % all elements - row1

The problem must be in line beginning with datevec

Brace indexing is not supported for variables of this type.

Error in location (line 18)
datevec = cell2mat(datenum{:});       % Umwandlung von Cell in Vector

How can I solve it?

And am I right that I can not substract an number from each element of a cell?

The variable datenum is not a cell array and thus, the error. Can you provide the data mat file? Also, What is that you are trying to do?

Oh yes, it's a double.

I want to substract the first element from all elements of this variable.

Answer 1

[KSSV]

datevec = cell2mat(datenum);   

Or check

class(datenum)

It should be already a converted to double.

[KSSV]

I want to substract the first element from all elements of this variable.

iwant = datenum-datenum(1) ;

thank you :)
