Hi I was coding when I had this error:
Time_msg_match = string(Time_msg_match);
Error using string
Conversion from cell failed. Element 61649 must be convertible to a string scalar.
>> Time_msg_match(61649)
ans =
1×1 cell array
{2×1 double}
How can I concadenate this 2x1 double?
I wrote:
Time_msg_match1 = num2str(cat(1, Time_msg_match{:}));
But the result is not what I wanted. Thanks in advance

Try this to create 2 separate variables out of that 1x2 cell array
Time_msg_match1 = Time_msg_match{1};
Time_msg_match2 = Time_msg_match{2};

I did not get what you tried to do but look what I have when I code
>> Time_msg_match = Time_msg_match';
>> Time_msg_match = string(Time_msg_match)
Error using string
Conversion from cell failed. Element 61649 must be convertible to a string scalar.
>> Time_msg_match(61649)
ans =
1×1 cell array
{2×1 double}

But I have deleted this line and it has worked so it is resolved. Thank you. Now I want to use this to index a duration array but I am gonna look by myself to do this. Once again thank you!!!!!

It looks like this is what you want:
x=Time_msg_match(61649);
x=x{1};

@vicente Noguer, did you overlook my request?
Also, a specific numerical example using the first 2 or 3 rows of your cell array would be helpful. Help us to help you.

You are ignoring the advice that Image Analyst is giving you. That is not smart.
Also, did you try making a it a double array instead of a cell? You will notice that my code will still do something usefull. It brings you only a single step away from the array you need.
