信号属性和索引
R2026a检查和修改数据和信号属性以及选择数据子集
使用 DSP System Toolbox™ 中的信号属性和转换模块检查和修改信号属性，如采样时间、复/实性、维度和数据类型。您也可以使用各种选择器模块选择数据子集和解构信号，并使用 Flip 和 Overwrite Values 模块修改这些数据。
模块
 | Check Signal Attributes | Error when input signal does or does not match selected attributes exactly |
 | Inherit Complexity | Change complexity of input to match reference signal |
 | Data Type Conversion | 将输入信号转换为指定的数据类型 |
 | Reshape | 更改信号的维度 |
 | Flip | 垂直或水平翻转输入 |
 | Multiport Selector | Distribute arbitrary subsets of input rows or columns to multiple output ports |
 | Overwrite Values | Overwrite submatrix or subdiagonal of input |
 | Selector | 从向量、矩阵或多维信号中选择输入元素 |
 | Variable Selector | Select subset of rows or columns from input |
