由上例可知,MATLAB认识所有一般常用到的加(+)、减(-)、乘(*)、除(/)的数学运算符号,以及幂次运算(^)。 小提示: MATLAB将所有变数均存成double的形式,所以不需经过变数宣告(Variabledeclaration)。MATLAB同时也会自动进行记忆体的使用和回收,而不必像C语言,必须由使用者一一指定.这些功能使的MATLAB易学易用,...
Enter the variable names to be used in the C header file. The particular filter structure determines the variables that are created in the file *lengthvariables contain the total number of coefficients of that type. Note Variable names cannot be C language reserved words, such as “for.” ...
