Purpose Assert variable is vector
Syntax mbvector(n)
Description The statement
mbvector(x)
causes the MATLAB Compiler to impute that x is a vector. At run-time, if
mbvector determines that x holds a nonvector value, mbvector issues an error
message and halts execution of the MEX-file.
mbvector causes the MATLAB interpreter to check whether x holds a vector
value. If
x does not, mbvector issues an error message and halts execution of
the M-file. The MATLAB interpreter does not use
mbvector to impute x.
Note that
mbvector only tests x at the point in an M-file or MEX-file where an
mbvector call appears. In other words, an mbvector call tests the value of x only
once. If
x becomes a nonvector after the mbvector test, mbvector cannot issue
an error message.
mbvector defines a vector as any matrix whose dimensions are 1-by-n or n-by-1.
All scalars are also vectors (though most vectors are not scalars).
Example This code in MATLAB causes mbvector to generate an error message because
the dimensions of
n are 2-by-2:
n = magic(2)
n =
1 3
4 2
