Error Using == Mpower Matrix Must Be Square

Thank you. When I have a matrix, x, and try to get different values for each x (given y = (x^2)+b), I get this error. ??? Covered by US Patent. A = 'hi | Error: A MATLAB string constant is not terminated properly. http://projectdataline.com/error-using/error-using-sym-mpower-matrix-must-be-square.html

You cannot do it this way: >> volumes = cube.volume ??? If the error is not fatal the code may even continue, but instead displaying the error as a message or it could be converted to a warning. krnhseya, Feb 20, 2008 Oct 15, 2009 #6 Sarah1287 Help with integrating function in Matlab Hi I'm trying to integrate a function func1 in Matlab but I keep getting errors I 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.

They must match if you want to replace a specific portion of an existing variable. An Error Occurred Unable to complete the action because of changes made to the page. A tag is like a keyword or category label associated with each thread.

In order to avoid the error, you must format 'cube.volume' as an array upon assignment. >> volumes = {cube.volume} You can also write in a separate assignment for each cube but Newsgroups are used to discuss a huge range of topics, make announcements, and trade files. As a reminder, here are some common functions that cannot be performed and what MATLAB returns (along with a warning for each one): a/0 = Inf if a > 0, -Inf For MATLAB's built-in functions, this information is found in the documentation, or by typing >> help functionname It is a good idea to set up some comments so that the help

Having an extra END in a 'switch' statement gives a message that you used the 'case' keyword illegally, because MATLAB thinks you ended the switch statement early, and 'case' has no but it seems like that my if,while,and other statements are not working because of how t is in matrix.

Besides: You are using a loop but i has no influence on the calculations, i guess there is something fundamental wrong with your code.

You cannot call a function with too many input arguments either: >> A = plus(1,2,3) ??? Not the answer you're looking for? The array power operator A.^n raises each element of A to the nth power, and therefore has no restrictions on the dimensions of A. A = 1+3+ | Error: Expression or statement is incomplete or incorrect.

Otherwise, you get the message: ??? It is necessary to know the nature of the input and output arguments of a given function in order to call it. You'll notice that if you tell MATLAB to display cube.volume, it will display both values, but reassign the variable ans each time, because it is treated as two separate variables.

If you want to simply square each element of X you should write X.^2. > > > > Roger Stafford thanks so much R Stafford I got another error wrt dimensions. Unfortunately, there are so many supplied functions in the base product plus installed toolboxes, remembering all of them is impossible so use which proposedname if you have any doubt the name To compare two strings you must use the strcmp function: >> 'AA' == 'AaA' ???

In this case the return would be the empty [] array as there are no subscripts matching false in the defined set of [1 2] as A has been defined above.
