Equação integral de Volterra

Multi tool use
Em matemática, uma equação integral de Volterra é um tipo especial de equação integral. Tais equações são divididas em dois grupos, referenciados como do primeiro e do segundo tipo.
Uma equação de Volterra do primeiro tipo é expressa na forma
- f(t)=∫atK(t,s)x(s)ds,{displaystyle f(t)=int _{a}^{t}K(t,s),x(s),ds,}

enquanto uma equação de Volterra do segundo tipo é dada por
- x(t)=f(t)+∫atK(t,s)x(s)ds.{displaystyle x(t)=f(t)+int _{a}^{t}K(t,s)x(s),ds.}

Na teoria dos operadores e na teoria de Fredholm, as equações correspondentes são denominadas operadores de Volterra.
Uma equação integral de Volterra é uma convolução, se
- x(t)=f(t)+∫t0tK(t−s)x(s)ds.{displaystyle x(t)=f(t)+int _{t_{0}}^{t}K(t-s)x(s),ds.}

A função K{displaystyle K}
na integral é denominada núcleo (em inglês: kernel).
Tais equações podem ser analisadas e resolvidas utilizando transformadas de Laplace.
As equações integrais de Volterra foram introduzidas por Vito Volterra, e então estudadas por Traian Lalescu em sua tese de doutorado 1908, Sur les équations de Volterra, sob orientação de Charles Émile Picard. Lalescu escreveu em 1911 o primeiro livro sobre equações integrais.

This question is a follow up of this one. I am trying to run a command through the command line on a remote machine running Windows 7 from a workstation running Debian in an SSH session on that machine. The setup is basically as follows: debian box 1 === (SSH) ===> debian box 2 === (RDP) ===> Windows 7 I have tried running rdesktop from debian box 2 : rdesktop <Windows 7 box network address> -u username -p password -r disk:local="./TestRDP" -s "cmd.exe /K net use C: \\tsclientlocal & C:\test.bat & logoff" but cmd.exe is not launched on the remote device. I have also tried to open up cmd.exe on its own: rdesktop <Windows 7 box network address> -u username -p password -s "cmd.exe" but the terminal is not launched upon login ( rdesktop successf...

Assumed I want to draw three simple graphs based on the following illustration: How can I plot those three graphs? I've tried to create something like this: Minimum Working Example (MWE): documentclass{standalone} usepackage{pgfplots} begin{document} begin{tikzpicture} begin{axis}[domain=0:1] addplot+[no marks, samples=100] {exp(3*x)}; addplot+[no marks, samples=100] {(-exp(3*x)+20)}; end{axis} end{tikzpicture} end{document} Screenshot of the current state: Description of the issue: However, I don't get the point on how to figure out the function of the third graph as well as how to clip the graphs in x and y direction to align them centered in the plot. It is not necessary to be completely precise, the accuracy of my upper template w...

So, my friend has been trying to install Matlab 2018b and he has encountered the following message just after the installation reaches 100%. Matlab installation additional configuration steps message I did some digging around in the Matlab forums and found out that to use the additional components, one should install a compiler and then use the following commands: mex -setup C mex -setup C++ Can anyone help me regarding this error? If this is indeed the solution then how can I execute those steps? Also, he says that even if he presses next, he cannot use matlab. The OS in use is Windows 10.
installation matlab
