WebIf you use the cell function to define a fixed-size cell array, you cannot use coder.varsize to specify that the cell array has a variable size. For example, this code causes a code generation error because x = cell (1,3) makes x a fixed-size,1-by-3 cell array. ... x = cell (1,3); coder.varsize ( 'x' , [1 5]) ... WebThe first dimension is fixed at size 3. The second and third dimensions are unbounded. Growing an Array by Using (end + 1) To grow an array X, you can assign a value to X (end + 1). If you make this assignment in your MATLAB ® code, the code generator treats the dimension you grow as variable-size.

WebJan 26, 2024 · In my application I am using a fixed size image that exactly matches the data size so it should not be performing scaling. One of the purposes of my application is for users to closely scrutinize an image to look for artifacts in the underlying data, so it is important that the MxNx3 uint8 array is faithfully produced on the screen.
