This article explains the key points of manipulating MATLAB matrices when starting I = imread('sample.jpg') R = dft1(I) I get this particular error: Error using * MTIMES is not fully supported for integer classes. At least one input must be scalar. To compute elementwise TIMES, use TIMES (.*) instead.I = imread('sample.jpg'); R = dft1(double(I)); Minor Note This code is quite clever, and it (by default) applies the 1D DFT to all columns of your image. The output will be a matrix of the same size as I where each column is the 1D DFT result of each column from I.

Introduction | Computing with MATLAB. The description goes here. MATLAB is the program we're going to use to implement and to analyze our mathematical models 6 You just need to cast the data to double, then run your code again. Basically what the error is saying is that you are trying to mix classes of data together when applying a matrix multiplication between two variable. Specifically, the numerical vectors and matrices you define in dft1 are all of a double type, yet your image is probably of type uint8 when you read this in through imread. This is why you're getting that integer error because uint8 is an integer class and you are trying to perform matrix multiplication with this data type with those of a double data type. Bear in mind that you can mix data types, so long as one number is a single number / scalar. This is also what the error is alluding to. Matrix multiplication of varaibles that are not floating point (double, single) is not supported in MATLAB so you need to make sure that your image data and your DFT matrices are the same type before applying your algorithm. when i type this equation in MatLab, I get the following error: x=linspace(0,8*pi,1000); y=x*sin(x); ???
