I have a coloumn of strings and I want to extract the numbers after the equal signs in an array. May I know how can I do that? Thank you.

"POINT_0_0=294.397"

"POINT_0_1=294.560"

"POINT_0_2=294.459"

"POINT_0_3=294.294"

"POINT_0_4=293.635"

v=str2double(extractAfter(X,'='));

is one way. For more difficult cases look at the new(ish) @doc:pattern function
