WebStateflow ® charts can detect changes in the values of data and expressions between time steps. You can: Use change detection operators to determine when a variable changes to or from a value. Use edge detection operators to determine when an expression rises above or falls below a threshold. WebDescription example tf = hasChangedFrom (data,value) returns 1 ( true) if the value of data is equal to value at the beginning of the previous time step and is a different value at the beginning of the current time step. Otherwise, the operator returns 0 ( false ). Examples expand all Detect Change in Matrix Detect Change in Matrix Element
