# How can I get display the result in a table GUI matlab

Asked by Kesni savitri on 14 May 2013

I am student in chemical Engineering, I am using MATLAB to solve eight differential equations describing nitrogen transformation. and I used GUI, i have a trouble to display nitrogen dynamic result in a table GUI. i want after i click the pushbutton, i get the result in a table.

So How can I get MATLAB to created a table that shows the concentrations of each transformation nitrogen??

I'm new in GUI matlab and would appreciate some help to do this.

as i understand you table could a .txt? and u are using GIDE to create the GUI

below the callback of your button you must write the code:

example:

```%define the variables that you want in the table
```
`    a=handles.a  `
```%if the variables comes from other place into the guy use handles to define and to call the value
```
```b=handles.b
c=handles.c
```
```%now format the table that contains 3 columns
file=('yourtable.txt');
fid = fopen(file, 'a');
fprintf(fid,'%u %u %6.0f ',a,b,c);
```
```%if you want to use a header in your table put this line below fid
```
```fprintf(fid,'value_a value_b value_c');
```

is very important to correctly define the values a, b,c below their respective callbacks, always used handles.yourvalue to move this values into the different callbacks of the GUI

thanks for your answered,. the result nitrogens consentration that i want in table gui, not from other file, but get from the calculate differential equation that solve with ODE45. there is 8 differential equation. y(1), y(2),..... y(8)..

_in pushbutton callback ,,

opts=odeset('Refine',10); [t,y]=ode45(@nitrogen,[0 2160],... [0.01 0.1 0.8 0 0 0 3.47 5.2]);

axes(handles.N_graphic)

% i get show the plot

Plot(handles,t,y,'konsentrasi nitrogen','waktu simulasi (jam)','konsentrasi (mg N / L)');

but, how can i get the result in table?

```table_handle = uitable('Position', ..... );
```
```table_as_cell = num2cell(YourMatrix);
```
```set(table_handle, 'Data', table_as_cell);
```

"set(table_handle, 'Data', table_as_cell);"

that you mean 'Data' is load from other file? the result nitrogens consentration that i want in table gui, not from other file, but get from the calculate differential equation that solve with ODE45 in this script.

```YourMatrix = [t, y];
table_as_cell = num2cell(YourMatrix);
table_handle = uitable('Position', ..... );
set(table_handle, 'Data', table_as_cell);
```

Data is not loaded from another file: it is loaded from the variable "table_as_cell" which is constructed in the lines above from your existing data.

yes, it works, thanks a lot Walter Roberson :)
