区分大小写:MATLAB是区分大小写的,所以myVariable和myvariable被视为两个不同的变量。 长度限制:虽然MATLAB对变量名的长度没有严格的硬性规定,但为了代码的可读性和兼容性,建议变量名不要过长。 避免使用关键字:不能使用MATLAB的关键字(如if、else、for、while等)作为变量名,否则会导致语法错误。你可以使用iskeyword...
A valid variable name begins with a letter and contains not more thannamelengthmaxcharacters. Valid variable names can include letters, digits, and underscores. MATLAB keywords are not valid variable names. To determine if the input is a MATLAB keyword, use theiskeywordfunction. ...

Trying to do a heat conduction simulation my and my IF statement not working I have a variable called 'b' which equal to 'maximum timestep - 1' and I want to use and IF to record maximum temperature The IF statement not working when I use IF == b, but works with IF = 9999...
If any random variable is constant, its correlation with all other variables is undefined, and the respective row and column value is NaN. P— P-values matrix P-values, returned as a matrix. P is symmetric and is the same size as R. The diagonal entries are all ones and the off-diago...
