I import a text file using textscan and use vertcat to assign each line of the file its own cell. I am working with data to where it says something like: take off time 0.102 sec sensor1 initiated .361 sec, -31 (mv) sync at 50 ms and this continues for about 42 rows of data. My end goal is to separate all the numeric data from the words. For example have an array that would show [.102; .361 -31; 50;....]. I have tried regexp and sscanf but have had no luck.
