How do I analyse an array of strings?

I have imported data into the program and need to analyse and simplify it. Within that, I have an array of strings that correspond to the calibration type. I need to write a function that checks where the calibration changes and display the corresponding time. I tried using strcmp but to no avail. How can I iterate over an array of strings?

You iterate over the array of strings similarly to any other array, but you have to be careful with the way of handling the elements.

Could you please paste a sample of your array of strings and the code you are using to handle the data?

Particularly, is it a character array or cell array of character (cell strings)?

If the latter, you'll likely find

of particular interest.

Again, however, awaiting details as David says to have much hope of anything more specific to offer.

I have the strings stored as a column of a matrix of a structure.

The looping code is:

SWCal = [];
for i=StartFile:EndFile
if i_SWCal>0

       i_SWCal = [SWCal; UD.Truck(iT).DataBasic(i).HistVal(:,i_SWCal)];
    end

I need to check where the Calibration changes. I tried with a cell initialisation as well but it is not looping the strings. I checked this in the workspace.

The other loops are all for numeric values, for example:

VehSpeed = [];
for i=StartFile:EndFile
if i_VS>0
        VehSpeed = [VehSpeed;UD.Truck(iT).DataBasic(i).HistVal(:,i_VS)];

I am not understanding how to change the initialisation and the looping command for the column of strings.
