The Matlab workspace is limited in size, depending on your system. We reached the workspace limit with a rowing study (10 participants, 1 kHz sampling rate, 20 variables, 10 minutes duration). Although the extracted data fits very well in the workspace, the raw data does not. Therefore, a solution is needed with fast access to specific variables. This is needed for feature extraction and later display of data.
Three approaches were used to solve this problem,
