### matlab plot table in figure

To plot a table in MATLAB, you can use the `uitable` function. Here is an example of how to create a table and plot it in a figure:

```matlab```% create example data
data = [1 2 3; 4 5 6; 7 8 9];

% create a figure
figure;

% create a table in the figure
t = uitable('Data', data);

% set the position of the table
t.Position = [50 50 200 100];
``````

In this example, we first create an example data matrix `data`. We then create a new figure using the `figure` function. We create a table within the figure using the `uitable` function and pass in the data matrix. We set the position of the table using the `Position` property. Finally, we can customize the appearance of the table using additional properties of the `uitable` object, such as `ColumnName` or `RowName`.

### Can you plot a table in MATLAB?

Yes, you can plot a table in MATLAB using the “uitable” function. The “uitable” function creates a table UI component in the MATLAB Figure window. Here’s an example code to create a simple table with two columns and three rows:

```matlab```% Define table data
data = {'John', 25; 'Jane', 30; 'Bob', 35};

% Create a figure window
figure

% Create a table UI component
t = uitable('Data', data, 'ColumnName', {'Name', 'Age'});

% Set the position and size of the table in the figure
t.Position = [20 20 260 72];
``````

This code will create a table with two columns, “Name” and “Age”, and three rows of data. You can customize the appearance of the table by changing the position, size, font, and color properties of the “uitable” object.

### How to convert table to array in MATLAB?

In MATLAB, you can convert a table to an array using the `table2array` function. Here’s an example:

Let’s say you have a table named `myTable` with three columns of data:

```lua```>> myTable = table([1; 2; 3], ['a'; 'b'; 'c'], [true; false; true], 'VariableNames', {'Column1', 'Column2', 'Column3'})

myTable =

3×3 table

Column1    Column2    Column3
_______    _______    _______

1         'a'         1
2         'b'         0
3         'c'         1
``````

To convert `myTable` to an array, you can use the `table2array` function:

```ruby```>> myArray = table2array(myTable)

myArray =

1     97      1
2     98      0
3     99      1
``````

In the resulting array `myArray`, each row corresponds to a row in `myTable`, and each column corresponds to a variable in the table. Note that the second column of `myTable` is a character array, which is converted to its ASCII code representation in the resulting array.

### How extract xy data value from MATLAB figure?

To extract xy data values from a MATLAB figure, you can use the “datacursormode” function in MATLAB. Here are the steps:

1. Open the figure containing the data you want to extract.
2. In the command window, type “datacursormode on” to activate data cursor mode.
3. Click on the data point you want to extract in the figure.
4. A data cursor will appear at the clicked point, displaying the x and y values.
5. To extract the data values, right-click on the data cursor and select “Export Data Cursor”.
6. Choose the format you want to export the data in (e.g. workspace variable, Excel file, etc.).
7. Save the exported data.

Alternatively, you can use the “ginput” function to select points on the figure and extract their xy values. Here are the steps:

1. Open the figure containing the data you want to extract.
2. In the command window, type “[x, y] = ginput(n)” where “n” is the number of data points you want to extract.
3. Click on each data point in the figure.
4. The x and y values of each clicked point will be stored in the “x” and “y” variables, respectively.
5. Use the extracted data as needed in your MATLAB script or analysis.

### Plot table – MATLAB

In MATLAB, you can plot a table using the `uitable` function. Here’s an example code that creates a table and plots it:

```matlab```% Create a 4x3 table
data = {'John', 25, 'Male'; 'Emily', 32, 'Female'; 'Sam', 18, 'Male'; 'Rachel', 27, 'Female'};
column_names = {'Name', 'Age', 'Gender'};
t = uitable('Data', data, 'ColumnName', column_names);

% Set the position and size of the table
t.Position = [50 50 300 100];

``````

This code creates a 4×3 table with column names “Name”, “Age”, and “Gender”. The table data is stored in the `data` variable. The `uitable` function is used to create the table, and the `Data` and `ColumnName` arguments are used to specify the table data and column names.

The `Position` property of the table is used to set the position and size of the table on the figure. In this example, the table is positioned at `(50, 50)` and has a width of 300 and height of 100.

Finally, the `ColumnHeadersVisible` property is set to `'off'` to hide the column headers. You can set this property to `'on'` if you want to show the column headers.

### Print table MATLAB

To print a table in MATLAB, you can use the `table` function. Here is an example:

```matlab```% Create some example data
name = {'John', 'Mary', 'David'};
age = [25, 30, 40];
height = [1.75, 1.60, 1.85];

% Create a table
T = table(name', age', height', 'VariableNames', {'Name', 'Age', 'Height'});

% Display the table
disp(T);
``````

This code creates a table with three columns (‘Name’, ‘Age’, ‘Height’) and three rows of data. The `disp` function is used to display the table in the command window.
