pull row data from excel in matlab

There are multiple ways to pull row data from Excel in MATLAB. One way is to use the xlsread function to read Excel data and extract the row(s) of interest.

Here's an example of extracting the 4th row of an Excel file:

main.m
% Import the Excel file
filename = 'example.xlsx';
data = xlsread(filename);

% Extract the 4th row
row_num = 4;
row_data = data(row_num,:);
141 chars
8 lines

This code reads in the Excel file 'example.xlsx' using the xlsread function and stores the data in the variable data. To extract the 4th row, we simply specify the row number using the variable row_num and use MATLAB's colon operator : to grab all columns. The resulting row data is stored in the variable row_data.

If you want to write data back to Excel, you can use the xlswrite function. Here's an example of writing a row of data back to an Excel file:

main.m
% Create some row data
row_data = [1 2 3 4 5];

% Write the row data to a new Excel file
filename = 'new_data.xlsx';
xlswrite(filename, row_data, 1, 'A1');
156 chars
7 lines

This code first creates a row of data using the variable row_data. The xlswrite function is then used to write the row of data to a new Excel file called 'new_data.xlsx'. The 1 specifies the sheet in the Excel file to write to, and 'A1' specifies the cell location to write the data to.
