Assign 1. Assign the value 9.81 to the variable gravity_si, and the value 32.17 to the variable gravity_eng. 2. Create a row vector containing the elements 0.5772, 1.618, 2.718 and 3.1416. Assign it to the variable math_consts. 3. Create a row vector containing the values from 50 to a value less than or equal to 1 with a decrement of 2. Assign it to the variable r_vec1. 4. Create a row vector containing linearly spaced values from 0 to π with exactly 37 elements. Assign it to the variable r_vec2. 5. Create a column vector containing the elements 6.022x10^23, 1.381x10^-23 and 6.626x10^-34. Assign it to the variable science_consts. 6. Create a matrix containing the elements 10, 4, 7, 9 and 11 on the first column, the elements 12, 8, 2, 3 and 4 on the second column, and the elements 7, 0, 12, 6 and 5 on the third column. Assign it to the variable mat1. 7. Create a 6x8 matrix with all elements equal to zero. Assign it to the variable mat2. 8. Assign the word discrete as a character type to the variable chr1. 9. Assign the word mathematics as a string type to the variable str1. 10. Create a 2x2 string array containing the following terms: Generation and Transmission on the first row, and Distribution and Supply on the second row. Assign it to the variable str2. Access 1. Load the data from workshop1.mat. It contains the following variables: sclr, r_vec, c_vec, mat, chr and str. 2. Extract the seventh element of r_vec. Assign it to the variable r_vec_e7. 3.
