Hi Joel,
From my understanding, you want to input and output vectors and graph in an Excel sheet.
You can import data from an excel sheet by either using the Import Data button in the Home tab or by using the the readtable function -
data = readtable('file.xls')
If you want only a section of the data, then you can specify the range of the data to import -
data = readtable('file.xls','Range','A1:F4')
In order to write matrices and vectors into an excel file, you can use the writematrix function -
writematrix(data,'file.xls')
In order to export figures and plots to an excel sheet, you can use the MLGetFigure function. Write =MLGetFigure(width, height) in an Excel cell in order to copy the current open figure to that cell.
For more details, you can refer to the following documentations -
