Hey guys. I have a 5x5 matrix and this matrix concludes 25 different image(jpg).All images are 64x64. For explain A(1,1)=image1.jpg A(1,2)=image2.jpg... A(5,5)=image25.jpg. But when i want to use imshow(A) this error comes: imshow: IM must be an image or the FILENA...
This MATLAB function reads the first worksheet in the Microsoft Excel spreadsheet workbook named filename and returns the numeric data in a matrix.
I have a numerical array 'drop' setup in my Matlab workspace. I can read the array into an interactive Matlab script using the prompt: F = input(' Enter the matrix name: ') This works fine in a main script. However, when I place this same command inside a supporting function file ca...

Xlsread command in Matlabyou read the entire spreadsheet. Which means, that you can read an entire matrix as is, at once. E.g., from the MathWorks documentation:
To read this data into MATLAB, use this command: A = xlsread('testdata1.xls') A = 1 6 2 7 3 8 4 9 5 10 Example 2 — Handling Text Data The Microsoft Excel spreadsheet file testdata2.xls contains a mix of numeric and text data: 1 6 2 7 3 8 4 9 5 text xlsread puts a...
