需要用EXCEL软件来作具体为：>>t=0:1:1000;y=normpdf(x,0,1);u=int(y,0,t);plot(t,y)???Undefinedfunctionorvariable'x'.>>t=0:1:1000;y=normpdf(x,0,1);u=int(y,0,t);plot(t,y)???Undefinedfunctionorvariable'x'.用matlab是这样画的>>t=0:1:1000;x=0:1:1000;y=normpdf(x,0,1);u=int(y,0,t);plot(t,y)???Function'int'isnotdefinedforvaluesofclass'double'.
