2 views (last 30 days)
i was to read a coloumn from xlsx file which is simple to implement as following
columnB = xlsread(myExample.xlsx,'B:B'); % this works
but i m designing a app in appdesigner, i want to give option to user to input desired column name, i tryed this through
% lets suppose my text edit field is named as app.Columneditfield
columnB = xlsread(myExample.xlsx,'app.Columneditfield.Value:app.Columneditfield.Value');
% this gives error not a valid range
% because when '' is used to define range it does not pick >>app.Columneditfield.Value<<
% kindly guide

Assuming app.Columneditfield.Value is already a char, you can simply create the range like this:
Range=[app.Columneditfield.Value ':' app.Columneditfield.Value];
columnB = xlsread('myExample.xlsx',Range);

You forgot to leave in the spaces:
%You wrote:
Range = [app.ColumnEditField.Value':'app.ColumnEditField.Value];
%You should have written:
Range = [app.ColumnEditField.Value ':' app.ColumnEditField.Value];
