Offset

Specify the first input data as a scalar or a vector. The inputs to the In ports (In1, In2, … ) must be of the same size and data type.

If the input is fixed point, it must be a signed integer or a signed fixed point value with a power-of-two slope and zero bias.

Data Types: single | double | int8 | int16 | int32 | fixed point
Complex Number Support: Yes

Specify the offset value that the block uses to truncate the first input data as an integer. The offset value determines the number of samples the block removes or keeps at the beginning or at the end of the first data.

The inputs to the O ports (O1, O2, … ) must have the same data type. The block rounds any offset value that is a noninteger value to the nearest integer value. If the offset value is out of the [0 N] range, then the Action for out of range offset value parameter determines how the block behaves. N is the input vector length.

Specify the second input data as a scalar or a vector. The inputs to the In ports (In1, In2, … ) must be of the same size and data type.

If the input is fixed point, it must be a signed integer or a signed fixed point value with a power-of-two slope and zero bias.

The block returns the truncated data as a scalar or a vector. The length of the truncated data depends on the Output port length and the Output length parameters. If Output port length is set to Same as input, the truncated data has the same size as the input data. If Output port length is set to User-defined, then the Output length parameter determines the length of the output data.

There is one output port for each pair of In and O ports.

The truncated output has the same data type as the input data. When the output is fixed-point, it is signed only.

Use this parameter to specify which values the block discards and which values the block keeps from the input vector.

Select from the following:

Use the Number of input data-offset pairs parameter to specify the number of inputs to the block. The number of input ports is twice the scalar value you specify in this parameter. For example, if you enter 3, input ports In1, O1, In2, O2, In3, and O3 appear on the block.

Use this parameter to specify the length of the output vectors. If you select Same as input, the output vectors have the same length as the input vectors. If you select User-defined, you can enter the desired length in the Output length parameter.

Enter a scalar that represents the desired length of the output vectors. If the desired output length that you specify is greater than the number of values that the block extracts from the input vector, the block zero-pads the end of the vector to reach the length that you specify.

Dependencies

This parameter is visible only if you set the Output port length parameter to User-defined.

Use this parameter to determine how the block behaves when an offset value is not in the range such that 0 ≤ offset value ≤ N, where N is the input vector length.
