Simulink merge

Help Center Help Center. The Merge block combines inputs into a single output.

The three-way model merge tool helps resolve two conflicting design changes made to the same model when working on a team project. While most differences are automatically merged by the tool itself, the ones that are marked in red require manual inspection. You can navigate between the conflicts and the tool allows you to visualize the differences side by side. The conflicts that require manual inspection can be instantly resolved within the tool itself. View more related videos.

Description The Merge block combines its inputs into a single output line whose value at any time is equal to the most recently computed output of its driving blocks. You can specify any number of inputs by setting the block's Number of inputs parameter. Note Merge blocks facilitate creation of alternately executing subsystems. See Creating Alternately Executing Subsystems for an application example. A Merge block does not accept signals whose elements have been reordered. For example, in the following diagram, the Merge block does not accept the output of the Selector block because the Selector block interchanges the first and fourth elements of the vector signal. If the Allow unequal port widths parameter is not selected, the block accepts only inputs of equal dimensions and outputs a signal of the same dimensions as the inputs. If the Allow unequal port widths option is selected, the block accepts scalars and vectors but not matrices having differing numbers of elements. Further, the block allows you to specify an offset for each input signal relative to the beginning of the output signal. The width of the output signal is. For example, the Merge block in the following diagram merges signals v1 and v2 to produce signal v3. In this example, the offset of v1 is 0 and the offset of v2 is 2 , resulting in an output signal six elements wide.

In Simulink, the merge block is documentation states. As clear as that statement is there are still questions about the behavior of the merge block. This post attempts to clarify those questions. The output from the subsystems is a simple enumerated constant equal to the subsystems name. In this example when the value of the driving signal is equal to abcs. D none of the subsystems are enabled.

Help Center Help Center. The Comparison Tool shows a report that only includes the differences between the two models, not the complete model hierarchies. Use the Next and Previous navigation buttons on the Comparison tab to step through groups of changes in the report:. The report goes through the changes one by one. If the selected item in the Left tree has a match, it will also be selected in the Right tree. The report highlights the selected items in both Simulink models if it is possible. To control highlighting in models, on the Comparison tab, in the Highlight section, select or clear the check box Always Highlight.

Help Center Help Center. The Merge block combines inputs into a single output. The output value at any time is equal to the most recently computed output of its driving blocks. Specify the number of inputs by setting the Number of inputs parameter. Use a Merge block to interleave input signals that update at different times into a combined signal in which the interleaved values retain their separate identities and times. To combine signals that update at the same time into an array or matrix signal, use a Concatenate block. Always use conditionally executed subsystems to drive Merge blocks, without any intervening blocks. Ensure that at most one of the driving conditionally executed subsystems executes at any time step. Do not specify the block execution priority of a Merge block. For all conditionally executed subsystem Outport blocks that drive Merge blocks, set Output when disabled to held.

The source of the constant value is a grounded signal. The Allow unequal port widths check box must be cleared. In this case, the output will be the initial value of the subsystem that is enabled when the simulation starts. Run the simulation to see the output of the Merge block on the Scope. Description Related Resources Three-Way Model Merge The three-way model merge tool helps resolve two conflicting design changes made to the same model when working on a team project. Allow unequal port widths — Clear this parameter. Default: 'off'. You have a modified version of this example. This example shows how to use conditionally executed subsystems and the Merge block to combine two inputs into a single output. For example, a single initiator could be a Stateflow chart executing function-call subsystems that are connected to a Merge block.

As clear as that statement is there are still questions about the behavior of the merge block. The Merge block is a bus-capable block. Like this: Like Loading Connect the output of the two conditionally executed subsystems to the inputs of the Merge block. The inputs can be virtual or nonvirtual bus signals subject to these restrictions:. Select the China site in Chinese or English for best site performance. Block Parameter: InitialOutput.
