String 正弦波串接
您好,我正试图创建一个标题,其中包括我的正弦波方程与变量String 正弦波串接,string,string-concatenation,scilab,String,String Concatenation,Scilab,您好,我正试图创建一个标题,其中包括我的正弦波方程与变量 % Set up initial parameters pi = 3.14; % Make a variable called pi, and set it equal to 3.14 A = 1985; % Set the amplitude (A) equal to 5 f = 7/3; % Set the frequency (f) equal to 10 p =
% Set up initial parameters
pi = 3.14; % Make a variable called pi, and set it equal to 3.14
A = 1985; % Set the amplitude (A) equal to 5
f = 7/3; % Set the frequency (f) equal to 10
p = pi/9; % Set the phase (p) equal to 0
% Create a time axis
dt = 0.1; % Set the time step to be relatively small
t = [0 : dt : 2.*pi]; % Create a list of time points from 0 thrugh 2*pi in steps of dt
% Calculate the sine wave
y = A.*sin(f.*t+p);
y
% Graphical Display
plot(t,y,'ko-')
xlabel('Time, sec', 'fontsize', 6)
ylabel ('Amplitude', 'fontsize', 6)
strA = msprintf('%1.1f', A);
strf = msprintf('%1.1f', f);
strp = msprintf('%1.1f', p);
titlestr = 'y = ' + strA +' .* sin( ' + strf + ' .* t + ' + strp + ')'
title(titlestr, 'fontsize', 6)
以下是我迄今为止所做的工作。
绘制这个方程时,我没有得到标题。
请帮忙
谢谢。您正在使用哪个版本的Scilab?它适用于我的5.4.0 顺便说一下,您应该使用%pi而不是声明pi,Scilab使用//作为注释,而不是%
