The From Workspace block can read array format data that is written by the To File block. You must transpose the array data before the From Workspace block reads that data. The source file contains consecutive time stamps at the beginnings of columns, followed by the corresponding data. The transposed data contains consecutive time stamps at the beginning of rows, followed by the corresponding data. To provide the required format, use MATLAB commands to load and transpose ( ) the MAT-file (see Reshaping a Matrix). You can then use a From Workspace block to access the data loaded into the workspace. Resave the transposed data if needed to avoid retransposing it again later
