intro to analytical programming -Matlab

We collect data for different type of milk. The data is recorded in a table T, with columns:

Country = [“CA”; “CA”; “US”;…]

state = [“ON”; “BC”; “OHIO”,…]; # province or state

fat= [1; 2; 3;…]; # fat percentage in %

quality = [2; 1; 5; …]; # the larger the better quality.

1. Code to view the data for “CA” (Canada)
2. Code to add one new type of milk, from MB, Canada, fat percentage is 10%, and quality is 4.
3. Code to update the “state” column, change “BC” to “AB”.
4. Code to find which milk has quality greater than 4.
5. Code to find which milk has quality greater than 4 and from “ON”.

For my understanding, you can select the required content Boolean Indexing

As an example

load patients.mat
T = table(Gender,Smoker,Height,Weight);
NewTable= T(T.Smoker==true,:) % return all the rows having Smoker = true

Similarly change according to usecase
