Use the contains function to find text in rows of a string array. census1905 contains a
few rows of simulated census data for the year 1905. Each row contains a name, year of
birth, and number of times that name was given in that year.
census1905 = ["Ann Mary","1905","230";
"John","1905","5400";
"Mary","1905","4600";
"Maryjane","1905","304";
"Paul","1905","1206"];
Find the rows where the name is equal to Mary.
TF = (census1905(:,1) == "Mary");
census1905(TF,:)
ans = 1x3 string array
"Mary" "1905" "4600"
Find the rows where the name is a variation of Mary with the contains function.
TF = contains(census1905(:,1),"Mary");
census1905(TF,:)
ans = 3x3 string array
"Ann Mary" "1905" "230"
"Mary" "1905" "4600"
"Maryjane" "1905" "304"
