mbintvector (MATLAB Compiler)

MATLAB Compiler

mbintvector

Assert variable is integer vector

Syntax

```
mbintvector(n)
```

Description

The statement

```
mbintvector(x)
```

causes the MATLAB Compiler to impute that x is an integer vector. At run-time, if mbintvector determines that x holds a value other than an integer vector, mbintvector issues an error message and halts execution of the MEX-file.

mbintvector tells the MATLAB interpreter to check whether x holds an integer vector value. If x does not, mbintvector issues an error message and halts execution of the M-file. The MATLAB interpreter does not use mbintvector to impute x.

Note that mbintvector only tests x at the point in an M-file or MEX-file where an mbintvector call appears. In other words, an mbintvector call tests the value of x only once. If x becomes a two-dimensional matrix after the mbintvector test, mbintvector cannot issue an error message.

mbintvector defines an integer vector as any value that meets the criteria of both mbint and mbvector. Note that mbintvector considers integer scalars to be integer vectors as well.

Example

This code in MATLAB causes mbintvector to generate an error message because, although all the values of n are integers, n is a matrix rather than a vector:

n = magic(2)
n =
     1     3
     4     2
mbintvector(n)
??? Error using ==> mbvector
Argument to mbvector must be a vector.
