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
