**Finding the row and column number in a matrix MATLAB**

The xlsread ignores leading rows or columns of text. However, if a cell not in a leading row or column is empty or contains text, xlsread puts a NaN in its place in the return array, num . Note The full functionality of xlsread depends on the ability to start Excel as a COM server from MATLAB.... For a 2 dimensional matrix, it is the larger of the number of rows and columns. I had read in a tutorial that length gives the first non-singleton dimension, but this is incorrect according to the official MathWorks MATLAB documentation and appears to be the cause of a bug in a program that I am using.

Then I would use the following code to read it in. Note that the * character excludes reading in the string column.... 29/08/2018Â Â· Create a matrix. A matrix is a rectangular set of numbers that are arranged in multiple rows and columns. Code a matrix by listing a series numbers separated by spaces or commas per row within the command window.

**Replacing the row and column number with names for a**

Here we will use for loop for reading 3 sets of data and each time, it will read 7 rows and 5 columns. We will create a structure named mydata in the workspace to store data read from the file. This structure has three fields - time , month , and raindata array.... I have a script in which I use writetable() to write data to a row in an excel spreadsheet. I need to get the row number of the next empty row in the file, but I haven't found a solution on this site.

**Limit of TEXTSCAN for reading the number of rows of an**

I have a script in which I use writetable() to write data to a row in an excel spreadsheet. I need to get the row number of the next empty row in the file, but I haven't found a solution on this site.... q be able to re-use a number of simple programming templates for some common programming tasks. Outline . 1. % convert to 2 columns and 1 row per line . Reading a table of strings is more complex, since the strings have to be the same length. We can use the fgetl() function to get a line of text as characters, but we'll first need to find out the length of the longest string, then ensure

## How To Read The Row Number In Matlab

### In the attached file i want to read only the numeric data of the file so that i can plot X Y. But i am facing problem that how to offset the row having strings.

- I want to write a Matlab program to read these values then display a message 'type of conductor? then takes the values from the desired row and uses it to find some values. eg: If b was chosen i want to find x=ln(r)=ln(.773) and y=GMR^2 if c was chosen x=ln(0.815)
- Here is on solution where I use for loop, I tried to optimize the number of iteration and the computational cost. If there is no corresponding value between B and A the row/col index return NaN.
