ploting 4 graphs for various constant values
显示 更早的评论
Hello, i want to write code for function x=a*exp(b), where b=0:2*pi, 'a' is positive value entered by user. This should be four times, i mean 4 values of a entered by user so 4 graphs drawn on window.
clear all; close all;
for i=1:4
a=input('write positive a:', 's') b= 0:2*pi; x=a*exp(b); subplot(2,2,i),plot(x) end
However this code doesn't work well, i mean it draws completely the same for all values of a!! and more strangely when i write a=10 it gives me an error msg:
Error using * Inner matrix dimensions must agree. x=a*exp(b);

Hi,
you used input with a second argument 's', so a is interpreted as a string and not a number
for getting a string :
a=input('write positive a:', 's')
class(a)
for getting a number:
a=input('write positive a:')
class(a)
