**How to make a contour plot of a matrix consisting of 1 and**

I have a matrix of 361*181 dimention, which contain NaN and some values.... nancumsum(), nancumprod() This week, instead of Picking a single file for highlighting, I would like to pose a couple of questions. Many years ago, in 2007 shortly after I started working for MathWorks, I needed at one point to calculate the cumulative sum of a vector, ignoring NaNs.

**How do I make a mesh or surface plot that is clear in**

I have a vector of datapoints containing some NaNs. I'd like to interpolate the NaNs only if there are 3 or less consecutive NaNs. i.e. interpolate over short datagaps but not long ones. how to build a working model of a tsunami Unfortunately you can't remove nan's from a matrix because all rows and columns must be the same size -- you can't have "ragged" edges. The best you can do it to replace them with something, like 0 or …

## How To Clear Nans In Matlab

nancumsum(), nancumprod() This week, instead of Picking a single file for highlighting, I would like to pose a couple of questions. Many years ago, in 2007 shortly after I started working for MathWorks, I needed at one point to calculate the cumulative sum of a vector, ignoring NaNs.

- When you don't know the name of a function in MATLAB, try lookfor. lookfor nan will quickly give you the names of some functions that work with NaNs, as well as giving you the first line of their help blocks.
- My code so far is below. I have the code so that it skips the first 19 lines and starts at line 20. However, I need to remove the NaN values that are in my data like Columns = [10;0.04500;0;NaN;NaN…
- If the surface or mesh data has a NaN (not-a-number) in it, then the location of the NaN will be blank (just as NaNs in 2-d plots leave blanks).
- I have a matrix of data I'm trying to fit a surface to, which contains a larger number of NaNs. When i use the 'sftool' tool, it says 'Ignoring NaNs in data' (which is exactly what I want) and works fine.
