~ 逻辑 not 逻辑关系函数 指令 含义 xor 不相同就取1,否则取0 any 只要有非0就取1,否则取0 all 全为1取1,否则为0 isnan 为数NaN取1,否则为0 isinf 为数inf取1,否则为0 isfinite 有限大小元素取1,否则为0 ischar 是字符串取1,否则为0 isequal 相等取1,否则取0 ismember 两个...
matlab里面的取整函数(fix,round,floor……,在对数据进行处理时,有时我们需要对含有小数的数据进行取整处理,本例分享matla里面常用的几种取整函数,fix、roud、floor、ceil
, equal to (\lstinline!==!), not equal to (\lstinline!~=!) \item Element-wise AND (\lstinline!&!) \item Element-wise OR (\lstinline!|!) \item Short-circuit AND (\lstinline!&&!) \item Short-circuit OR (\lstinline!||!) \end{enumerate} \caption{MATLAB operator precedence list.} ...
Scripts and function names cannot have spaces in them.ParallelR.mis a validmatlabfilename, whereasParallel R.mis not. Practice Problems 1. Create a script calledCurrentSolverthatexpects to have the variables V and R defined. It should create a variable called I and set it equal to the curren...
not uniquely defined, and the two functions mod and rem each compute a different variation. The mod function produces a result that is either zero or has the same sign as the divisor. The rem function produces a result that is either zero or has the same sign as the dividend...
== equal; ~= not equal. 对于scalars, relation运算若为真,也结果是1,否则是0。 对于同样大小的矩阵,relation运算的结果也是一个有0和1组成的矩阵,他们是对原来两个矩阵的对应项分别计算的结果。如果所有项都为1,则relation运算作为if或者while的条件时值为1,否则为0。
The knowledge learned here is: If the variable is not reassigned at the beginning, then the number will become larger and larger after repeated operations. disp() is also an output statement, which can output values with newlines. Not equal to use "~=" to express. mod() is used to take...
Re-meshing is needed to evaluate the optimum structure in a post-process only, and thus does not affect the mesh during optimization. 3. Results Here, we first compare the results obtained from linear and non-linear optimization. Then, we elaborate on the force limit, where the results are...
当x>0时,sign(x)=1。 > 小整理:MATLAB常用的三角函数 sin(x):正弦函数 cos(x):馀弦函数 tan(x):正切函数 asin(x):反正弦函数 acos(x):反馀弦函数 atan(x):反正切函数 atan2(x,y):四象限的反正切函数 sinh(x):超越正弦函数 cosh(x):超越馀弦函数 ...
By using an indexing expression on the left side of the equal sign, you canreplacecertain elements of the vector. v([2 3 4]) = [10 15 20]% Replace some elements of vv = 16 10 15 20 2 11 7 14 Usually, the number of elements on the right must be the same as the number of ...
