bad = isnan(x) x(bad) = 0 This is pretty basic stuff. First make an array of true/false values, then use this to set selected elements to zero. If x is your matrix then use the isnan function to index the array: x( isnan(x) ) = 0 If you do it in two steps it's probably clearer to see what's happening.Es habitual combinar las dos líneas anteriores de código en una única línea: X = zeros (size (A)) Cree un arreglo de ceros que tenga el mismo tamaño que un arreglo existente. Clonar el tamaño de un arreglo existente. Calling nonzeros on the matrix a will return a vector of elements.However, if it is your desire to replace all values in the matrix with either 0 or 1, where 1 is anything non-zero, you can simply create a logical matrix like so: A = A ~= 0 If it is your desire to also have this be a double matrix, you can easily do that by the uplus (unary plus) operator or cast to double 1: A = + (A ~= 0) %// or %A. Learn more about row, column, matrix, array, add, remove MATLABTo remove a single zero from each row of a matrix and rebuild the new matrix of nonzero entries, try the following code: garcia venegas If you give it a try in MATLAB you'll see that getting the appropriate sized output takes a bit of thinking.

How to add a first row and a first column of. A (badRows, :) = Of course you could compress all that into a single line if you want but I just used separate lines for tutorial purposes so you can see what's going on. zeroRows = any (A=0, 2) badRows = nanRows | zeroRows.B = zeros (d1,d2,d3.) or B = zeros ( ) returns a n array of zeros with dimensions d1 -by- d2 -by- d3 -by. B = zeros (m,n) or B = zeros ( ) returns an m -by- n matrix of zeros. An error message appears if n is not a scalar. 0 Comments Show -1 older comments Hide -1 older commentsDescription B = zeros (n) returns an n -by- n matrix of zeros. clear allI have an array of data of size 5.I have to pad zeros to set the size as 10.How to add zeros of size 5.Help me please.

So,if you matirx is this case, the code as first one.
The same is true for extending any other array type.You just show an simple matrix, which has the same zeros in each row. So what you are trying to do is: list = % DON'T DO THIS! v = 1 creates such an array with a single value. It's double type is an array of double-float values. So for example, MATLAB doesn't have a double-float type. (The struct array is also a heterogeneous storage, but each element of the array is a struct with the same fields, so it's still consistent that way.) contains elements of different types), because each cell is an array of arbitrary type. The cell array is the only one that is heterogeneous (i.e. The difference between these is of course what is inside each array. There are numeric, logical, character and cell arrays, as well as struct arrays and object arrays. The makers of MATLAB have some really good online tutorials for beginners (it's free!). It's worth while taking a little bit of time to learn about how MATLAB handles data if you will be programming in MATLAB. If you try to convert Python 1-to-1 to MATLAB, you'll run into all sorts of problems.
