I need help on this matlab homework and need these problems done. Thanks.

1. Create three structure arrays called cars, trucks, and motorcycles. Give each element of the structure array 4 values. Let one of the values be a string called name and then let the other values be unique or semi-unique to the array such as bed length, number of wheels or handlebar width etc. Fill each structure array with data so that the array length is 3 then display each array to screen. Make sure they are structure arrays 2. Create a 10-element cell array. Fill each odd element of the array is a string describing the element number. For example: one' three' 'nine'. Fill each even numbered element of the array with a matrix that has a random size [nrows, ncols] from 1 to 5 and is filled with integers that is the element number For example: [2 2 2; 2 21, [4 4 44;444 4; 4444], etc. Display the data on the screen. Can this be accomplished with an array of structures where each structure has two elements; the value and the string equivalent as in the cell array? (Y/N) 3. Create a 200x200 matrix of integers and initialize it to zero. Set the value of each element to be 128exp(-d/20) where d is the radial distance from the center of the image/matrix (100,100). Display the image with a 256-element gray colormap using the command, image ( and also imagesc. Note and explain the differences in the comment section (Make it short
