delete the first and last character inside a char

Hi. How can I do to delete the 0 and A present in each row of the cell?

values = {'08126A';'05354A';'01406A';'09630A'};

I am using this code but would like to delete only the first 0.

charact = {'08126A';'05354A';'01406A';'09630A'};
pat = num2cell('0A');
charact = erase(charact,pat);

charact = {'08126A';'05354A';'01406A';'09630A'};
y=regexprep(charact,'0(\d*)A','$1')

y = 4×1 cell array
    {'8126'}
    {'5354'}
    {'1406'}
    {'9630'}

You can easily extend this code to work for other leading and trailing characters (and other characters in the middle):

charact = {'08126A';'05354A';'01406A';'09630A'};
y=regexprep(charact,'.(.*).','$1')

y = 4×1 cell array
    {'8126'}
    {'5354'}
    {'1406'}
    {'9630'}

That's neat!

Hi @Alberto Acri,

As per my understanding, you are interested in eliminating the 0s and As from each row of the cells.In order to delete the 0 and A present in each row of cell, you might want to follow these steps:

• Declare the values cell array (as done).

values = {'08126A';'05354A';'01406A';'09630A'};

• Use the strrep function to replace 0 and A with empty character ''.

% Remove '0' from each cell
values = strrep(values, '0', '');

% Remove 'A' from each cell
values = strrep(values, 'A', '');

• Display the resultant values cell using 'disp'.

disp(values);

Find the MATLAB strrep documentation here: https://in.mathworks.com/help/matlab/ref/strrep.html

Thank you.

That will strip all zeros from the vectors, not just leading zeros.

values = {'08126A';'05354A';'01406A';'09630A'};
% Remove '0' from each cell
values = strrep(values, '0', '');
% Remove 'A' from each cell
values = strrep(values, 'A', '')

values = 4×1 cell array
    {'8126'}
    {'5354'}
    {'146' }
    {'963' }
