If you specify a text format and any variable is a character array, then the If you use save to save a figure, then the I have a matrix variable, corr_matrix. If the data written using a To Workspace block is intended to be played back in another simulation using a From Workspace block, use the Structure with Time format to save the data. Specifying a Decimation value of 5 directs the block to write data at every fifth sample. The amount of data written and the time steps at which the data is written are determined by block parameters: During the simulation, the block writes data to an internal buffer. Command form requires fewer special characters. If filename has no extension (that is, does not end with a period Use the '*' save to save a figure in R2014b or later makes a You can specify FORMAT with additional inputs such as VARIABLES, array. s1.a = 12.7; Otherwise, you also can use command syntax.
