This value must be 1 if a 3-D array is specified in the Signal parameter. Samples per frame The number of samples, M o, to buffer into each output frame. Initial output The value to output until the first trigger event is received. Tunable, except in Simulink's external mode. Trigger type The type of event that triggers the block's execution. Signal The name of the MATLAB workspace variable from which to import the signal, or a valid MATLAB expression specifying the signal. If there are not enough samples at the end of the signal to fill the final frame, the block zero-pads the final frame as necessary to ensure that the output for each cycle is identical (e.g., the ith frame of one cycle contains the same samples as the ith frame of any other cycle). If Cyclic Repetition is specified, the block repeats the signal from the beginning after generating the last frame.If Holding Final Value is specified, the block repeats the final sample for the duration of the simulation after generating the last frame of the signal.If Setting To Zero is specified, the block generates zero-valued outputs for the duration of the simulation after generating the last frame of the signal.(The block does not extrapolate the imported signal beyond the last sample.) The Form output after final data value by parameter controls this behavior: When the block has output all of the available signal samples, it can start again at the beginning of the signal, or simply repeat the final value or generate zeros until the end of the simulation. For matrix outputs (M o-by-N or M-by-N), the Initial output parameter value can be a vector of length N to repeat across all rows of the initial outputs, or a scalar to repeat across all elements of the initial matrix outputs. For single-channel signals, the Initial output parameter value can be a vector of length M o or a scalar to repeat across the M o elements of the initial output frames. Between trigger events, the block holds the output value constant at its most recent value (i.e., no linear interpolation takes place). The Initial output parameter specifies the output of the block from the start of the simulation until the first trigger event arrives. Either edge triggers execution of the block when either a rising or falling edge (as described above) occurs.Falling edge triggers execution of the block when the trigger input falls from a positive value to zero or a negative value, or from zero to a negative value.Rising edge triggers execution of the block when the trigger input rises from a negative value to zero or a positive value, or from zero to a positive value.The triggering event at the input port is specified by the Trigger type pop-up menu, and can be one of the following: The Samples per frame parameter must be set to 1, and the output is always sample-based.

When the Signal parameter specifies an M-by-N-by-P array, the block generates a single page of the array (an M-by-N matrix) at each trigger time. For convenience, an imported row vector (M=1) is treated as a single channel, so the output dimension is M o-by-1. For M o=1, the output is sample-based otherwise the output is frame-based. The frame size is specified by the Samples per frame parameter, M o, and the output when triggered is an M o-by-N matrix containing M o consecutive samples from each signal channel. When the Signal parameter specifies an M-by-N matrix (M 1), each of the N columns is treated as a distinct channel. The Signal parameter specifies the name of a MATLAB workspace variable containing the signal to import, or any valid MATLAB expression defining a matrix or 3-D array. The Triggered Signal From Workspace block imports signal samples from the MATLAB workspace into the Simulink model when triggered by the control signal at the input port ( ).
