MATLAB Help

[redsox]

Those who are proficient in MATLAB, can you please help with this problem. I am trying to execute the following code but I keep getting this message:

R1=4


R2=4


G=[.25 -.25 0;-.25 .50 0;1 0 0]


Gin=inv(G);




for t=0:.005:1


	{




		Vs =[0;0;(10*sin(7*t))];


		B=[0;0;Is];


		I=[(Vs/R1) 0 0];


		V=(I+B)*Gin;


		end


		}

The error message I get is this:

??? Error: File: A2.m Line: 11 Column: 12


The expression to the left of the equals sign is not a valid target for an assignment.

Can someone please help me in regards to this. I am actually in a hurry. Thank you.

I don't know what MATLAB is, much less what that code does, but you have a space after the "Vs" property where the others don't have spaces. Other than that, the error sounds as if it's something that's not been declared properly - like if you haven't specified what R1, for example, is.

Not proficient in MATLAB, but does "Is" need to be defined?

And is line 11 really the 11th line in the code post?

And are semi-colons needed between (Vs/R1), 0 and 0?

I was able to find out what the problem was. The code inside the for-loop should not be inside the parenthesis.

FYI - MATLAB is an expensive software that mainly utilizes MATRIX to solve problems. It has a hell of a lot of features. I am using it for college (Electrical Engineering major) and just started using them. Seems pretty interesting even though I hate coding.

you can't have a number in the file name. take the number out and rename the file to something like 'atwo' or 'anew' or something

well, nmind if that fixed the problem. when i had to use matlab we could never have a number in the filename.
