x = sqrt(16) % defining x and initializing it with an expression 1. MATLAB将执行上面的语句,并返回以下结果: x = 4 1. 2. 请注意: 一旦一个变量被输入到系统中,你可以引用它。 变量在使用它们之前,必须有值。 当表达式返回一个结果,不分配给任何变量,系统分配给一个变量命名ans,以后可以使用。 例如...
The value of the expression after switch is a numeric variable or a character variable. By comparing these values with the numeric value or string value after the case, the statement body under which case is executed if the value of which case is the same as that of all cases If the val...
(isstring(str) && ~(isscalar(str) && (strlength(str) > 0))); end function s = mysize(x, dim) if isnumeric(dim) || islogical(dim) if isscalar(dim) s = size(x,dim); else s = size(x,dim(1)); for i = 2:length(dim) s = s * size(x,dim(i)); end end else s = ...
Validation functions do not change input values in any way, so to avoid data type conversion, use one or more validator functions instead of a data type to restrict the input. For example: To avoid conversion of strings to numeric values, usemustBeA,mustBeFloat, ormustBeNumeric. ...
if expression, statements, end evaluates an expression, and executes a group of statements when the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks...

whileexpression,statements, endevaluates anexpression, and repeats the execution of a group of statements in a loop while the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. ...
Dynamic expressions must return a logical or numeric value. Conditional Operator Description Example expr1|expr2 Match expression expr1 or expression expr2. If there is a match with expr1, then expr2 is ignored. '(let|tel)\w+' matches words that start with let or tel. (?(cond)expr) ...
Matrices are two-dimensional arrays that contain only numeric data or mathematical expressions where the variables of the expression have already been assigned numeric values. Thus, 23.2 and x2 are allowed, peter is allowed if it is a numeric constant but not if it is a person's name. Thus...
