I am using MatlabR2014b in my Dell Latitude E6420 laptop. My laptop specifications are 3rd Generation Intel® Core™ i5 Processor,8 GB ram,500 gb Hard disk with 50 gb of free space in C drive,Intel® HD Graphics 3000,2.50 Ghz CPU clock speed. Why my Matlab is running slow even with these high end specifications?

Which OS do you have? Windows? If yes, 32bit or 64bit? If 64bit, which MATLAB version, 32bit or 64bit?

Windows 10 64 bit and obviously matlab is also 64bit

@Walter Roberson No my memory monitor is not showing less on memory. My laptop is just using 3.3gb out of 8gb when i am working on simulink.

Have you tried using simulink accelerated mode? http://www.mathworks.com/help/simulink/ug/choosing-a-simulation-mode.html

1.Open SIMULINK 2.Open "Model Configuration parameters" from "Simulation" menu on top (or) use shortcut key CTRL+E. 3.Select "solver" tab. 4.In "solver options" try using different types of "solvers" (available solvers are ode45(Dormand-Prince),ode23tb(stiff/TR-BDF2)...... e.t.c) 5.For me simulation time takes nearly 3 hours when i used "ode45(Dormand-Prince)" and just 1 minute when i used "ode23tb(stiff/TR-BDF2)".
