Vector/matrix block input conversion

Select the diagnostic action to take when Simulink^® software detects a vector-to-matrix or matrix-to-vector conversion at a block input.

Category: Diagnostics

Default: none

none: Simulink software takes no action.
warning: Simulink software displays a warning.
error: Simulink software terminates the simulation and displays an error message.

Simulink software converts vectors to row or column matrices and row or column matrices to vectors under the following circumstances:

If a vector signal is connected to an input that requires a matrix, Simulink software converts the vector to a one-row or one-column matrix.
If a one-column or one-row matrix is connected to an input that requires a vector, Simulink software converts the matrix to a vector.
If the inputs to a block consist of a mixture of vectors and matrices and the matrix inputs all have one column or one row, Simulink software converts the vectors to matrices having one column or one row, respectively.
