Test matlab
Test intro text. Nice code below:
clearvars;close all;clc
Fs = 48000;
%T = 0.005;
f0 = 1000;
P_0_rms = 1;
P_ref_rms = 20*10^(-6);
T = 3*(1/f0);
Ts = 1/Fs;
tVec = [0:Ts:T-Ts];
x_0 = sqrt(2)*sin(2*pi*f0*tVec);
x_ref = P_ref_rms*sqrt(2)*sin(2*pi*f0*tVec);
figfont = 16;
figline = 4;
fig1 = figure(1);
subplot(1,2,1)
hold on
grid on
plot(1000*tVec, (10^6)*x_ref,'linewidth',figline)
plot(1000*tVec,P_ref_rms*(10^6)*ones(length(tVec),1),'linewidth',figline,'LineStyle','--')
xlabel('Time (ms)','FontSize',figfont)
ylabel('Amplitude (\muPa, micro-Pascals)','FontSize',figfont)
title({['1 kHz sinusoidal acoustic pressure signal']; ['Level: 20 \muPa (RMS); L_p = 0 dB (SPL)']},'FontSize',figfont)
ylim([-30,30])
set(gca,'FontSize',figfont-2,'YTick',[-30:5:30])
subplot(1,2,2)
hold on
grid on
plot(1000*tVec, x_0,'linewidth',figline)
plot(1000*tVec,ones(length(tVec),1),'linewidth',figline,'LineStyle','--')
xlabel('Time (ms)','FontSize',figfont)
ylabel('Amplitude (Pa, Pascals)','FontSize',figfont)
title({['1 kHz sinusoidal acoustic pressure signal']; ['Level: 1 Pa (RMS); L_p = 94 dB (SPL)']},'FontSize',figfont)
ylim([-1.6,1.6])
set(gca,'FontSize',figfont-2,'YTick',[-1.6:0.2:1.6])
set(fig1,'Position',[223.0000 224 1100 474.1350])
And some footer-type text
