I have loaded some struct data into a container I'm calling 'CMData' in my function.
I want the function to access the array of data in 'CMData.Car_ax.data' which I'm passing in a char array to the function as an argument called 'signal'
I want to perform some other functions such as Standard Deviation, and some boundary value checks in which I want to iterate over the contents of the struct array but Matlab is doing this on the char array rather than the fields of struct CMData. For example, if I count the number of elements in 'signal' I get 18, which is the number of characters that make up 'CMData.Car_ax.data' when really I'm looking for a value of 3250.
How do I change this so that I am using a struct reference and not a char array?
