MATLAB: I wanna change the assigned value format’s long in this function (value) “set(handles.edit1, ‘String’, value)”

format long appearence for set(handles...) function

%for example x=-0.134635523018792

%for gui presentation

set(handles.edit1, 'String', x)

%in gui x=-0.1346355 %7 numbers after the dot is appeared but I want to see whole numbers after the dot

It is very surprising that

set(handles.edit1, 'String', x)

shows any string at all, when x is a double value. Actually only strings and cell strings are accepted.

This shows x with 16 digits:

x = -0.134635523018792;
set(handles.edit1, 'String', sprintf('%.16g', x))

Note that it cannot be guaranteed, that you see "all" digits, because there are no accurate decimal representations for the numbers, which are store in binary format internally. See also: FAQ: Why is 0.3-0.2-0.1 ~= 0

MATLAB: Is there any way to “clean” a single row of a uitable

To clear a list of rows from a table, copy the entire table into a local variable, empty the desired rows, and then reassign the local table back to the UI table.

% Create demo UItable
d = {'Male',52,9;'Male',40,0;'Female',25,9};
f = figure;
handles.TablaDatosElementos = uitable(f,'Data',d,'Position',[20 20 262 204]);
% 1) copy current table to a local variable
t = get(handles.TablaDatosElementos,'Data'); 
% 2) Identify which row numbers to clear
rowIdx = [1,2];  % Clear rows 1 and 2
% 3) Clear those rows in the local variable
t(rowIdx,:) = cell(numel(rowIdx),size(t,2));
% 4) reassign updated table to the GUI 
set(handles.TablaDatosElementos,'Data',t);
