## MATLAB help

Hello friends,
I am new to MATLAB and I have been asigned a task in MATLAB to simulate basic equation..
I have no idea how to start..
The equation is

Arterial pressure= Mean arterial pressure - h*7.46 (h= height)

Can you tell me how to do please?

thankx

 what are you trying to do? plot it? if so here's an example to try first: a=3 b=5 x = [ 1, 2, 3, 4, 5 ] y = a*x + b plot(x,y) y2=x*x plot(x,y2) ...
 but how can i relate this to my equation? yes..I have to plot it ..H is variable and Arterial pressure is output

## MATLAB help

so h is the independent variable just like the x in my example where I set
x = [ 1, 2, 3, 4, 5]

there is also a way to set x via a range:
x=1:5:0.1

where x will vary from 1 to 5 by 0.1 increments ie x=[1.0, 1.1, 1.2, 1.3 ... 5]

this should give you enough to solve the problem and plot your results via plot(h,ap)
 Thank you man ..now it is clear.. I have one more question.. I am trying to do same in simulink but can you tell me how to import my variable H in simulink? i mean which block shall I use?
 sorry I'm not a matlab user. I learned it once in a course on computational physics using java as an alternative to java simulations. Hopefully someone else will answer. In any event here's a link I found that may point you in the right direction: http://www.mathworks.com/support/tec...1900/1902.html
 Thanks again
 Hi am new to MATLAB...I need to find the coordinates of a figure in a plot but i dont know how ... kindly explain
