expression of anif...endblock, logical operators∧|behave as short-circuit operators. This behavior is the same as&∧||, respectively. Since&∧||consistently short-circuit in conditional expressions and statements, it is good practice to use&∧||instead of∧|within the expression. For example...
For example, x = 42; if exist('myfunction.m','file') && (myfunction(x) >= pi) disp('Expressions are true') end The first part of the expression evaluates to false. Therefore, MATLAB does not need to evaluate the second part of the expression, which would result in an undefined ...

You must specify more than one input argument withassertif you want MATLAB to convert special characters (such as\t,\n,%s, and%d) in the error message. Example:'Assertion condition failed.' Value that replace the conversion specifiers inmsg, specified as a character vector, string scalar, or...
if ismember(img(trial), condition1) imgType = 'condition1'; elseif ismember(img(trial), condition2) imgType = 'condition2'; end 这里的imgType只是举例,你也可以直接将判断的结果放入到保存所有数据的matrix中。 4.2 structure对象 structure可以储存不同种类的对象,可以非常方便地存储实验数据。详细信息...
Hello I have doubts in using if condition in matlab.I have to perform the following operation in a cell. Final={ S1ifB{i}=11 S1if B{i}=10 S2if B{i}=01 S2if B{i}=00 I have the 2 bit binary values as a 128x17 cell. How to perform this and create a new matrix Z where ...
The execution method is that if the condition in the conditional expression is established, the loop statement is executed, and if the expression is not established, the statement after end is executed. 分支结构Branch structure 1.if...end结构 ...
