X= true(n)creates ann-by-n逻辑矩阵的编码矩阵。

When you create the codistributed array in a communicating job orspmd块，该函数在每个工人上创建一个数组。如果您在交流作业或spmdblock, the array is stored only on the worker or client that creates the codistributed array.

By default, the codistributed array has the underlying typedouble。

X= true(SZ1，...，SZN)creates ansz1-by-...-by-szNcodistributed array of logical ones whereSZ1，...，SZNindicates the size of each dimension.

X= true(sz)creates a codistributed array of logical ones where the size vectorszdefines the size ofX。For example,真的(codistributed([2 3]))creates a 2-by-3 codistributed array.

X= true(___,codist)使用Codistributor对象codistto create a codistributed array of logical ones. You can use this syntax with any of the input arguments in the previous syntaxes.

Specify the distribution of the array values across the memory of workers using the codistributor objectcodist。有关创建codistibutor的更多信息，请参阅Codistributor1d和Codistributor2DBC。

X= true(___,codist,"noCommunication")creates a codistributed array of logical ones without using communication between workers. You can specifycodist或者编码师，“ Nocommunication”, but not both.

When you create very large arrays or your communicating job orspmdblock uses many workers, worker-worker communication can slow down array creation. Use this syntax to improve the performance of your code by removing the time required for worker-worker communication.

X= true(___,"like",p)uses the arrayp返回一个逻辑上的编码阵列。您可以指定datatype或者"like", but not both.

The returned arrayXhas the same sparsity asp。
