Getting values from balance into matlab

I am trying to get values from my balance into matlab to be plotted over time. I am using the following functions

>> s = serial('COM4', 'BaudRate', 9600);

>> fopen(s);

>> a = fscanf(s)

I get the following:

a =

'S S 98.98g

'

In the workspace it appears as a [name] and 1x18 char [value]

How can I convert the value 'S S 98.98g' to a number variable?

Try this:

number = sscanf(a, '%*c %*c %f%*c');

The * characters tell sscanf to ignore (not return) those fields. You can learn more in the documentation here: https://www.mathworks.com/help/matlab/ref/sscanf.html
