Hi Venkatesh Kumar,
The first step is to check if the Arduino hardware being used is connected to the computer and is accessible from MATLAB. To do this, follow the steps in this link - https://www.mathworks.com/help/matlab/supportpkg/connect-to-arduino-hardware.html.
To continuously read analog values from the Arduino hardware, making use of a loop can help. The following link has example code to continuously read analog values from one pin (“A0”) of Arduino and store them in a MATLAB matrix - https://www.mathworks.com/matlabcentral/answers/1881002-how-to-read-analog-data-instantaneously-from-arduino-to-matlab.
The matrix “dataMatrix” from the example code can then be written to an excel spreadsheet using the “writematrix” function. Execute the following command after the loop in the example code-
writematrix(dataMatrix, 'data.xls')
Refer to this link for more information on the “writematrix” function- https://www.mathworks.com/help/matlab/ref/writematrix.html#:~:text=Write%20Matrix%20to%20Spreadsheet%20File.
