Compare a string array to a character vector. As long as one of the variables is a string

array, you can make the comparison.

chr = 'Gemini';

TF = (str1 == chr)

TF = 2x3 logical array

0 1 0

0 0 0

Index into str1 with TF to extract the string elements that matched Gemini. You can use

logical arrays to index into an array.

str1(TF)

ans =

"Gemini"

Compare for inequality using the ~= operator. Index into str1 to extract the elements

that do not match 'Gemini'.

TF = (str1 ~= chr)

TF = 2x3 logical array

1 0 1

1 1 1

str1(TF)

ans = 5x1 string array

"Mercury"

"Skylab"

"Skylab B"

"Apollo"

"International Space Station"
