习题21 请读者先运行以下指令a=0;b=pi;t1=a:pi/9:pi;t2=linspace(a,b,10);T=t1*t2;F=find(T0);然后，请回答变量a、t1、T、F的维度、规模、长度分别是多少？t1完全等于t2吗？为什么？1）产生数据a=0;b=pi;t1=a:pi/9:pi;t2=linspace(a,b,10);T=t1*t2;F=find(T0); 2）罗列各变量的特征Na=ndims(a);Nt1=ndims(t1);NT=ndims(T);NF=ndims(F);Sa=size(a);St1=size(t1);ST=size(T);SF=size(F);La=length(a);Lt1=length(t1);LT=length(T);LF=length(F);fprintf(数组%7s%8s%8s%8sn,a,t1,T,F)fprintf(维度数%5d%8d%8d%8dn,Na,Nt1,NT,NF)fprintf(规模%5d
