Conversion to cell from double is not possible.

Best Answer

Somewhere in your code you have a line of the form

variable(index) = value;

where value is numeric. However, your variable is a cell array rather than a numeric array, and MATLAB cannot figure out how to convert the numeric value into a cell array to store it.

You probably instead want

variable{index} = value;

This is an outline of what is wrong; we would need to see your code to be sure.

MATLAB: How to extract value from .mat file

Hello Samah,

It's not entirely clear to me what you are looking for. If you have a MAT file that contains an array, and you want only the last element of the array, you could do something like this:

load myMatFile.mat myArrayName
val = myArrayName(end);

If using load, it is generally good practice to specify which variables are being loaded. This allows the code to be more readable by seeing where variables originate from.

You can also use the matfile function to access the data within the MAT file, without explicitly loading all variables. This only works for numeric data, and is most efficient if the MAT file was saved with the v7.3 setting or argument.

m = matfile('myMatFile.mat');
val = m.myArrayName(end);

Hope this helps!

MATLAB: Callback simulink library StopFcn

Hello! I have put your question through Google Translate -- I hope an English answer is fine...

Mask variables are, by design, only visible under the mask. For example, imagine you had 3 of these blocks in one model -- you would cause a variable conflict.

The way you could extract the block parameter into the base workspace is:

>> NomFichier = get_param('ModelName/BlockName','NomFichier');
