A more useful expression would be something like >> A(A==3) Attempting to use non-standard MATLAB syntax in your indexing will often result in the error: >> A(2::, 2) ???

A = 1+3+ | Error: Expression or statement is incomplete or incorrect. Solved Error using ==> mpower . One feature is that the names of variables and functions are case sensitive, and that one can alias builtin or user-written functions with variables of the same name. You cannot do it this way: >> volumes = cube.volume ???

Array Indexing errors[edit] Array indexing is a key component of MATLAB. There are thousands of newsgroups, each addressing a single topic or area of interest.

Messages are exchanged and managed using open-standard protocols. but it seems like that my if,while,and other statements are not working because of how t is in matrix.

Unfortunately missing [] is not the cause, since adding them causes more errors.

You cannot do that on the same line that the if/while statement is on. All assigned output arguments must also be of the correct class if you are replacing parts of an array that already exists (see the section on assignment for more on this). Tags can be used as keywords to find particular files of interest, or as a way to categorize your bookmarked postings. x=linspace(0,50,100); y = zeros(1,length(x)); for i = 1:length(x) h_5 = 184544783/4620170000; h_4 = (221/1483363330625).*y; h_3 = (1887/12500).*y; h_2 = 359187209/4620170000; h_1 = 91999/231008500000000000; a_13 = (91999/231008500000000000)./x; a_31 = 18606379625340700000/11891636430654839; a_32 =

It is often useful to pull up MATLAB's help (go to help -> product help or type doc into the command prompt) and do a search for the operation you want. IF the function is x^2- x*sin(x), do we need the period before the * in x*sin(x); I'm in need of the answer, asap! It is wise to calculate the determinant before attempting to take the inverse or, better, to use a method that does not require you to take the inverse since its not If you are using power function you might add a single dot after the parameter.
