Hi, is there a way to assign the outerposition property of a figure to a figure with a given handle? For example, if I wanted to define a figure as say figure 1, I would use: figure(1) imagesc(Arrayname) % I.e. any array I can also change the properties of a figure using the code: figure('Name', 'Name of figure','NumberTitle','o...
I have several .csv files with similar filenames except a numeric month (i.e. 03_data.csv, 04_data.csv, 05_data.csv, etc.) that I'd like to read into R. I have two questions: Is there a function in R similar to MATLAB's varname and assignin that will let me create/declare a variable name within a function or loop that will allow me to...

Is there a way to "declare" a variable with a particular user-defined type in MATLAB? zeros() only works for built-in numeric types. The only solution I've come up with involves using repmat() to duplicate a dummy object zero times: arr = repmat(myClass(), [1 0]) Without declaring variables this way, any code which does "arr(end+1) = ...
